U. of Basel Effort: Quantum Tech. to Benefit From Ultrathin Semiconductors Connected to Superconductors
For the first time, University of Basel researchers have equipped an ultrathin semiconductor with superconducting contacts. These extremely thin materials with novel electronic and optical properties could pave the way for previously unimagined applications. Combined with superconductors, they are expected to give rise to new quantum phenomena and find use in quantum technology.
Quantum Information Processing Gets Conventional-Like Memory Storage
New Laser-Assisted Non-Volatile Memory Based on 2D van-der-Waals Heterostructures The researchers designed and investigated a few-layer rhenium disulfide (ReS2) field-effect transistor with a local floating gate (FG) of monolayer graphene separated by a thin hexagonal boron nitride (h-BN) tunnel layer and applied it to non-volatile memory (NVM) devices. FG-NVM devices based on 2D van-der-Waals heterostructures […]
Columbia Engineering Pushes Forth In Many Quantum Directions With New Twistoptics Studies
Twistoptics—A New Way to Control Optical Nonlinearity Two slabs of boron nitride crystals are dynamically twisted with respect to each other. At certain angles, the incoming laser light (orange beam) can be efficiently converted to higher energy light (pink beam), as a result of micromechanical symmetry breaking. Nonlinear optics, a study of how light […]
Rice University: Spintronic Device Research to Improve Next-Generation Quantum Computers
Theory accelerates push for spintronic devices Rice models help ID materials for advanced electronics, computer memories A new theory by Rice University scientists could boost the growing field of spintronics, devices that depend on the state of an electron as much as the brute electrical force required to push it. Materials theorist Boris Yakobson and graduate student Sunny […]
