By combining standard through-the-lens viewing with a technique called scatterfield imaging, the NIST team accurately measured patterned features on a silicon wafer that were 30 times smaller than the wavelength of light (450 nanometers) used to examine them. They reported that measurements of the etched lines—as thin as 16 nanometers wide—on the SEMATECH-fabricated wafer were accurate to one nanometer. credit: NIST/Barnes (Recommended by Ed Perkins, posted by Yonhua Tzeng) To [...]
NIST Nanotechnology Seminar Series Next Generation Electricity Storage: Beyond Lithium Ion Batteries George Crabtree Director, Joint Center for Energy Storage Research (JCESR) Argonne National Laboratory University of Illinois at Chicago Wednesday, March 30th 10:30 AM Bldg. 215, Rm C103-106 A library of fundamental knowledge of the materials and phenomena of energy storage at the atomic and molecular level.The Joint Center for Energy Storage Research (JCESR) pursues high performance, low cost [...]
December 21, 2015 – Sub-60mV-Swing Negative-Capacitance FinFET without Hysteresis Was Demonstrated for the First Time Negative Capacitance FET (NCFET) can be viewed as a FET with built-in voltage amplification. The first ALD ferroelectric HfZrO2 based negative-capacitance FinFET with gate length as small as 30 nm was reported in IEEE International Electron Devices Meeting (IEDM 2015) in Washington, DC USA. Small-signal voltage was amplified by 1.6X maximum at the internal [...]
Researchers at the National Institute of Standards and Technology (NIST) have developed a fast, simple process for making platinum "nano-raspberries"—microscopic clusters of nanoscale particles of the precious metal. The berry-like shape is significant because it has a high surface area, which is helpful in the design of catalysts. Even better news for industrial chemists: the researchers figured out when and why the berry clusters clump into larger bunches of "nano-grapes." Read [...]
Yue Zhao et al., an international team of scientists at the U.S. Commerce Department's National Institute of Standards and Technology (NIST), demonstrated nanoscale whispering gallery electron resonance in graphene by using the probe voltage of a scanning tunneling microscope to create a circular pn junction in nanoscale area like a circular wall of mirrors to the electrons and similar to what happens to acoustic wave in the famous whispering gallery [...]
