Superconductivity seen in trilayer graphene Stanford University and University of California at Berkeley researchers discovered signs of superconductivity in stacking three-layer sheets of graphene, they report. “It’s definitely an exciting development,” says Cory Dean, a physicist at Columbia University. Dean notes that bilayer graphene superconducts only when the atomic lattices of ... » read more

Transparent film is stronger than aluminum Professor Ton Peijs of WMG at the University of Warwick and Professor Cees Bastiaansen at Queen Mary University of London came up with a new processing technique that produces a transparent polythene film said to be stronger than aluminum. The film could be used in displays, glazing, visors, and windshields, without adding significant weight. The d... » read more

In-Memory Computing Challenges Come Into Focus


For the last several decades, gains in computing performance have come by processing larger volumes of data more quickly and with superior precision. Memory and storage space are measured in gigabytes and terabytes now, not kilobytes and megabytes. Processors operate on 64-bit rather than 8-bit chunks of data. And yet the semiconductor industry’s ability to create and collect high quality ... » read more

Rubbery material for stretchable electronics Researchers at the University of Houston came up with a rubbery semiconducting material that they say could find applications in stretchable electronics, such as human-machine interfaces, implantable bioelectronics, and robotic skins. Cunjiang Yu, Bill D. Cook Assistant Professor of mechanical engineering at the University of Houston and correspo... » read more

EDA Grabs Bigger Slice Of Chip Market


EDA revenues have been a fairly constant percentage of semiconductor revenues, but that may change in 2019. With new customers creating demand, and some traditional customers shifting focus from advanced nodes, the various branches of the EDA tool industry may be where sticky technical problems are solved. IC manufacturing, packaging and development tools all are finding new ways to handle t... » read more

Interest Grows In Ferroelectric Devices


Ferroelectric FETs and memories are beginning to show promise as researchers begin developing and testing next-generation transistors. One measure of the efficiency of a transistor is the subthreshold swing, which is the change in gate voltage needed to increase the drain current by one order of magnitude. Measured in units of millivolts per decade, in conventional MOSFETs it is limited to k... » read more

What’s A Mott FET?


The unique physics of two-dimensional semiconductors offers the potential for new kinds of switches that could extend the usefulness of conventional MOSFETs into a variety of new areas. A MOSFET applies a voltage to one side of the gate capacitor. The resulting electric field in the channel shifts the band structure and facilitates or impedes the flow of carriers. So as devices shrink, the g... » read more

Deep learning device identifies airborne allergens To identify and measure airborne biological particles, or bioaerosols, that originate from living organisms such as plants or fungi, UCLA researchers have invented a portable device that uses holograms and machine learning. The device is trained to recognize five common allergens — pollen from Bermuda grass, oak, ragweed and spores from t... » read more
