Research Bits: June 4


Ultra-pure silicon Researchers from the University of Manchester and University of Melbourne developed a technique to engineer ultra-pure silicon that could be used in the construction of high-performance qubit devices that extend quantum coherence times. The highly purified silicon chips house and protect the qubits so they can sustain quantum coherence much longer, enabling complex calcul... » read more

Interfacial ferroelectricity in marginally twisted 2D semiconductors


Abstract "Twisted heterostructures of two-dimensional crystals offer almost unlimited scope for the design of new metamaterials. Here we demonstrate a room temperature ferroelectric semiconductor that is assembled using mono- or few-layer MoS2. These van der Waals heterostructures feature broken inversion symmetry, which, together with the asymmetry of atomic arrangement at the interface of tw... » read more

Week In Review: Design, Low Power


Tools Vtool released a new version of its Cogita visual debug platform. New features aim to provide faster debug capabilities, including visual representation of test results using log files as input, improved manipulation and navigation throughout big logs, ML algorithms to classify data and find the relationship between inputs, and the ability to merge and compare test flow of two different ... » read more

Maskless EUV lithography At this week’s 2020 EUVL Workshop, KJ Innovation will present more details about its efforts to develop a maskless extreme ultraviolet (EUV) lithography technology. Still in R&D, KJ Innovation’s maskless EUV technology involves a high-numerical aperture (high-NA) system with 2 million individual write beams. The 0.55 NA technology is targeted for direct-write l... » read more

Periodic table for molecules In what could propel the development of new materials, the Tokyo Institute of Technology has developed a periodic table for molecules. If the proposed concept is developed and adopted, the table could one day be used for creating new materials. It also may predict new materials for future use. This table is somewhat akin to the periodic table of elements, wh... » read more

Simulating quarks and gluons The U.S. Department of Energy’s Oak Ridge National Laboratory is simulating sub-atomic particles on the world’s most powerful supercomputer. The system is simulating these particles at speeds over 70 times faster than the predecessor. More specifically, Oak Ridge is simulating quarks and gluons on the recently-announced Summit supercomputer. In simple terms,... » read more
