Thermal lithography Using a technique called thermal scanning probe lithography, New York University (NYU) and others have reported a breakthrough in fabricating 2D semiconductors. With the technology, researchers have devised metal electrodes with vanishing Schottky barriers on 2D semiconductors based on molybdenum disulfide (MoS₂). Thermal scanning probe lithography, sometimes called t-... » read more

FinFET vs. FD-SOI pH sensors At the recent 2018 IEEE International Electron Devices Meeting (IEDM), TSMC and National Tsing Hua University presented a paper on an ion detector or pH sensor based on a 16nm finFET technology. Researchers have developed an advanced version of an ion-sensitive field-effect transistor (ISFET). Originally developed in the 1970s, ISFETs are pH sensors that are use... » read more

FISH metrology The University of Illinois at Urbana-Champaign and the Mayo Clinic have developed a new molecular probe for use in imaging cells in living organisms. The probe combines conventional fluorescence in situ hybridization (FISH) metrology techniques with compact quantum dots. This technology can measure and count ribonucleic acid (RNA) in cells and tissue without organic dyes. ... » read more

Can Graphene Be Mass Manufactured?

Since the isolation of graphene in 2004, the high mobility and unique transport properties of 2-dimensional semiconductors have tantalized physicists and materials scientists. Their in-plane carrier transport and lack of dangling bonds potentially can minimize line/edge scattering and other effects of extreme scaling. While 2-D materials cannot compete with silicon at current device dime... » read more

Computers that perceive human emotion As part of the growing field of “affective computing,” MIT researchers have developed a machine-learning model that takes computers a step closer to interpreting our emotions as naturally as humans do. Affective computing uses robots and computers to analyze facial expressions, interpret emotions, and respond accordingly. Applications include, for ... » read more

Single-atom storage Scientists at EPFL are working on a single-atom magnetic data storage device that takes advantage of quantum effects to provide dense storage. The team is using holmium, an element they've been exploring for years. "Single-atom magnets offer an interesting perspective because quantum mechanics may offer shortcuts across their stability barriers that we could exploit in t... » read more

Tandem solar reaches 25.2% efficiency In the push for ever-more efficient solar panels, researchers are turning to tandem, or double-junction, photovoltaics. Tandem solar panels use two different types of solar cell capable of absorbing different wavelengths of light stacked on top of each other to maximize the conversion of light rays into electrical power. Recently, two groups have reache... » read more

Compressing data in vehicles As the number of cameras in automobiles is on the rise with the move to autonomous vehicles, internal vehicle networks are being pushed to their limits from the flood of data. While special compression methods reduce the amount of video data, they also exhibit a high degree of latency for coding. But now, Fraunhofer researchers have adapted video compression in su... » read more
