Distinguished Lecturer Talk Title: 3D Radio-Frequency to millimeter wave heterogeneous system integration: Emerging nanotechnology for RF nanopackaging, the link between nanoscopic and macroscopic worlds?

 

Abstract:

Whether for niche applications (military, space, medical) or for high volume applications (portable devices, entertainment, automobile) the design of RF subsystems requires balancing packaging choices to meet demanding customer targets of cost, size and high performance.

In this context, numerous efforts have recently focused on heterogeneous 3D integration of components to subsystems for future RF to mmW applications. However major challenges remain and as a response, RF nanotechnology offer new opportunities. It enables new nanomaterials with unique RF properties due to their small dimensions and good transport properties for more efficient interconnects, EM shielding and thermal management.

The talk will start by introducing the future trends in RF to mmW electronics, highlighting limitations and opportunities that nanomaterials with associated nanotechnologies and additive manufacturing processes (such 3D printing) can help to overcome and take advantage of respectively.  The focus will be on what is actually done and will be done to pave the way for better 3D integration.

The talk will cover the latest developments of highly multidisciplinary approaches in

  • RF/thermal-mechanical simulations at nanoscale
  • intensive research investigations focused on carbon nanotubes, nanowires, graphene or other 2D materials
  • innovative RF nanopackaging approaches

A review of the state of the art will be given during the entire talk, in order to provide examples of tangible results.

Distinguished Lecturer Talk Title: Toward Highly Efficient Solar Water Splitting: A Concurrent Electrical, Optical, and Catalytic Design

 

Abstract:

Energy crisis is a broad and complex global topic. Natural resources such as gas and oil are in limited in supply. Development towards renewable resources is one of the most important technologies in the world. Currently, photocatalytic and photoelectrochemical (PEC) water splitting devices under the irradiation of sunlight have received much attention for the production of renewable hydrogen from water. Solar energy conversion and storage through photoelectrolysis of water using semiconductors as both light absorber and energy converter to store solar energy in simple chemical bond, H2, become highly desirable approaches to solving the energy shortage challenge.

We focus on the effort to develop an efficient Si-based PEC water splitting device. We introduce the surface textured Si heterojunction PEC cell consisting of ultrathin amorphous Si/crystalline Si as efficient and robust photoelectrodes. The solar to hydrogen conversion efficiency has been improved to 13.26%, which is the highest ever reported for Si-based photocathodes. Later on, we design the cascading energy band structure in Si via doping for facilitating carrier separation and novel electrode structures for 360° light harvesting for hydrogen generation with ultrahigh current densities of 61.2 mAcm-2. The cells have been further demonstrated with excellent hydrogen production rate. In addition, our method can significantly improve the stability of Si-based solar cells in water to sustain up to 300 hr. These multifunctional designs provide the potential for the future development in the renewable energy market.

Abstract: Biomedical Devices for Nano-Theranostics

Bioelectronics is referred to as an integration of biomolecules and electronics devices that combines theranostics with diagnostics and therapeutics, aiming to monitor the response to treatment, which would be a key part of precision medicine. The unique electronic, optical and catalytic properties of engineered nanoparticles pave the way to new applications particular in medicine and electronic industrials. On the other hand, various biomolecules exhibit the unique biological properties such as biorecognition, self-assembly properties. In my lab, we are integrating the physical and chemical properties of nanomaterials and the biological properties of biomolecules with MEMS/NEMS technology and analytical systems to develop highly sensitive miniaturized devices for biomedical sensing and noninvasive medical therapy. The lecture will outline our recent research activities for the fundamental study of physical and electrical properties of biomolecules such as cells, as well as the development of a new generation of micro/nano electronic devices. Several newly developed whole cell based devices will be introduced including: 1) rapid nanotoxicity assay using electronic cell impedance sensing system; 2). Neuron devices for monitoring single neuron cell and neuron tissue biological functions; 3) Electrical manipulation of cancer cell for noninvasive treatment of cancer cells.

Distinguished Lecturer Talk Title: Creating Green Nanostructures and Nanomaterials for Advanced Energy Nanodevices

 

Abstract:

Securing safe and cheap energy and using it effectively is a serious problem for modern society. As a solution to this, we are performing research on innovative green nanodevices. We are currently developing energy generation and storage devices, low-power-consumption devices, multifunctional nano-devices and nano-energy systems that use these devices. Manufacturing these nanodevices needs to be done precisely without damaging the nanostructures and by deriving the intrinsic characteristics of the nanomaterials and nanostructures. For the first time, such devices are made possible through the mastery of our unique intelligent nano-processes such as a super-low-damage neutral beam processes, pulsed plasma processes, and ultimate processing utilizing biotechnology.

In this lecture, we focus on bio-template and neutral beam etching fusion top-down process to realize nanoscale structures. The optical, electrical, spintronics and phononic characteristics have been already demonstrated in nanoscale structures. Our fabricated nanostructure can precisely control the transport of electron, hole, spin and phonon by diameter, height, gap and interlayer materials of the nanostructure respectively. Now, based on these results, we are trying to develop Quantum Nanostructure (QN) solar cells, QN thermo-electric conversion elements, QN Laser/LED, QN spin devices and so on.

Distinguished Lecturer Talk Title: Bridging the electronic, atomistic and mesoscopic scales in materials modeling using machine learning

 

Abstract:

Recent advances in machine learning (ML) and data science algorithms, along with high performance computing (HPC) capabilities, present unique opportunities to address cutting edge problems in material science. In parallel, modern supercomputers together with the availability of highly scalable atomistic simulation codes have begun to revolutionize the modeling and computational analyses of materials. Molecular dynamics (MD) is one such powerful technique, which has a broad user base. There are various flavors of MD from the highly accurate ab initio molecular dynamics (AIMD) to semi-empirical atomistic MD to more computational efficient coarse-grained (CG) models. There is still a substantial gap between AIMD, which are computationally intractable for large systems, and those based on classical force fields (atomistic and CG) that rely on pre-defined functional form for inter/intra atomic/bead interactions, which inherently limits their ability to capture physics for complex interfaces. This talk will focus on our machine-learning framework that bridges this gap by combining the accuracy and flexibility of electronic structure calculations with the speed of classical potentials. This framework enables accurate prediction of inter-atomic forces and thereby allow high fidelity dynamical and statistical simulations of reactive interfaces, properties and functionalities of new hybrid materials, as well as pathways and mechanisms of their operando synthesis and assembly.

Distinguished Lecturer Talk Title: Recent Results and Future Prospects for Mixed-Signal Neuromorphic Inference Accelerators

 

Abstract:

Recent advances in dense, continuous-state nonvolatile memories have enabled extremely fast, compact, and energy-efficient analog and mixed-signal circuits. Such circuits are perfectly suited, in particular, for hardware implementations of the inference operation in advanced neuromorphic networks, which requires massive amounts of dot-product operations with low-to-medium precision. In my talk, I will first review typical implementations of such mixed-signal circuits. I then describe some recent experimental demonstrations of prototype mixed-signal neuromorphic networks by our team, in particular, a mixed-signal inference accelerator with unprecedented speed and energy efficiency. The talk will be concluded by outlining some urgently needed work, in particular the development of high-performance general-purpose inference accelerators, and discussing our preliminary results in this direction.
