Research Bits: May 16


Germanium-tin transistor Scientists at Forschungszentrum Jülich, CEA-Leti, University of Leeds, Leibniz Institute for High Performance Microelectronics, and RWTH Aachen University fabricated a new type of transistor from a germanium-tin alloy. Charge carriers can move faster in the material than in silicon or germanium, which enables lower voltages in operation. “The germanium–tin syst... » read more

Week In Review: Design, Low Power


Arm advanced its progress toward an initial public offering, confidentially submitting a draft registration statement on Form F-1 to the U.S. Securities and Exchange Commission. The size and price range for the proposed offering have yet to be determined. Graphene IDM Paragraf acquired Cardea Bio, a maker of graphene-based biocompatible chips. Cardea has developed a biosignal processing unit... » read more

Power/Performance Bits: Nov. 16


Light-emitting memory Researchers from Kyushu University and National Taiwan Normal University propose a 'light-emitting memory' based on a perovskite that can simultaneously store and visually transmit data. The team used the idea in conjunction with resistive RAM (RRAM), in which states of high and low resistance represent ones and zeros. "The electrical measurements needed to check the r... » read more

Manufacturing Bits: Dec. 13


Phonon lasers A European consortium recently kicked off a new project that will develop a practical phonon laser. The European consortium, called PHENOMEN, will be coordinated by the Catalan Institute of Nanoscience and Nanotechnology (ICN2). Most chips perform functions using an electrical charge (electrons) or by light (photons). In comparison, a phonon “is a quantum of energy or a q... » read more
