Power/Performance Bits: Feb. 26


Integrated RRAM for edge AI Researchers at CEA-Leti and Stanford University have developed the first circuit integrating multiple-bit non-volatile Resistive RAM (RRAM) with silicon computing units, as well as new memory resiliency features that provide 2.3-times the capacity of existing RRAM. The proof-of-concept chip monolithically integrates two heterogeneous technologies: 18KB of on-chip... » read more

Internet of Ears for smart buildings Scientists at Case Western Reserve University proposed a new way for smart homes to determine building occupancy: sensors that 'listen' to vibration, sound, and changes in the existing ambient electrical field. "We are trying to make a building that is able to 'listen' to the humans inside," said Ming-Chun Huang, an assistant professor in electrical engi... » read more

Non-toxic photoluminescent nanoparticles Researchers from Osaka University developed a way to improve display technologies using non-toxic light-emitting nanoparticles. In trying to replace cadmium and other toxic materials used in quantum dots, scientists have turned to non-toxic nanoparticles that emit light in an efficient manner by creating I–III–VI semiconductors, such as silver in... » read more

World’s smallest transistor The Karlsruhe Institute of Technology (KIT) has developed what researchers say is the world’s smallest transistor. Researchers have devised a single-atom transistor. The transistor switches an electrical current via a single atom, which resides in a gel electrolyte. The device also works at room temperature. While others have developed single-atom transist... » read more

AI for solar materials In the search for better organic photovoltaic materials, researchers at Osaka University turned to machine learning to help identify candidates. While organic photovoltaics (OPVs) are promising on a cost basis, they do not yet have the required power conversion efficiency (PCE) necessary for commercialization. A key element in this is the semiconducting polymer layer. ... » read more

World’s coldest chip Using a network of nuclear refrigerators, the University of Basel and others claim to have set the record for the world’s coldest chip. Researchers have cooled a chip to a temperature lower than 3 millikelvin. A millikelvin is one thousandth of a kelvin. Absolute zero is 0 kelvin or minus 273.15 °C. In the experiment, researchers used a chip that includes a Coulomb... » read more

Redefining unit measurements At a recent meeting, the International Committee for Weights and Measures (CIPM) took the next step towards the expected redefinition of four base units within the International System of Units (SI). The SI base units include the following metrics or constants--meter, kilogram, second, ampere, kelvin, mole, and the candela. Here’s the fundamental constant... » read more

Concentrating photovoltaics Engineers at Penn State University and the University of Illinois at Urbana-Champaign tested a new concentrating photovoltaic solar system, which they say can produce over 50% more energy per day than standard silicon solar cells. In contrast to silicon solar panels, which currently dominate the market at 15 to 20 percent efficiency, concentrating photovoltaics (... » read more

Magnetic storage on one atom Scientists at IBM Research created a single-atom magnet and were able to store one bit of data on it, making it the world's smallest magnetic storage device. Using electrical current, the researchers showed that two magnetic atoms could be written and read independently even when they were separated by just one nanometer. This tight spacing could, the team hop... » read more
