Growing 2D TMDs on chips Researchers from Massachusetts Institute of Technology (MIT), Oak Ridge National Laboratory, and Ericsson Research found a way to “grow” layers of 2D transition metal dichalcogenide (TMD) materials directly on top of a fully fabricated silicon chip, a technique they say could enable denser integrations. The researchers focused on molybdenum disulfide, which is f... » read more

Power/Performance Bits: Dec. 7


Logic-in-memory with MoS2 Engineers at École Polytechnique Fédérale de Lausanne (EPFL) built a logic-in-memory device using molybdenum disulfide (MoS2) as the channel material. MoS2 is a three-atom-thick 2D material and excellent semiconductor. The new chip is based on floating-gate field-effect transistors (FGFETs) that can hold electric charges for long periods. MoS2 is particularly se... » read more

Healing perovskites Researchers at Brown University found that while perovskite solar cells can crack easily, they are also capable of healing those cracks. "The efficiency of perovskite solar cells has grown very quickly and now rivals silicon in laboratory cells," said Nitin Padture, a professor in Brown's School of Engineering and director of Brown's Institute for Molecular and Nanoscale... » read more

Sunny days slow 5G 5G networks promise a world of fast wireless data speeds and connected everything.  However, researchers at Embry-Riddle Aeronautical University and King Saud University found that hot, sunny weather could degrade 5G cellular transmissions by more than 15%. The researchers focused on how solar radio emissions would affect the unlicensed 60 GHz bands, part of the millimet... » read more

Exploring New Scaling Approaches


At the recent SPIE Photomask Technology + Extreme Ultraviolet Lithography 2017 conference, Semiconductor Engineering sat down to discuss semiconductor technology with Tsu-Jae King Liu, the TSMC Distinguished Professor in Microelectronics in the Department of Electrical Engineering and Computer Sciences at the University of California at Berkeley. More specifically, Liu discussed some of the new... » read more

Ad hoc "cache hierarchies" Researchers at MIT and Carnegie Mellon University designed a system that reallocates cache access on the fly, to create new "cache hierarchies" tailored to the needs of particular programs. Dubbed Jenga, the system distinguishes between the physical locations of the separate memory banks that make up the shared cache. For each core, Jenga knows how long it would t... » read more
