For this, they took inspiration from a pumping system intimately familiar to everyone: the human heart. Wed, 06 Sep 2023 11:23:57 EDT //www.koonmotors.com/releases/2023/09/230906112357.htm Pioneering beyond-silicon technology via residue-free field effect transistors //www.koonmotors.com/releases/2023/09/230905125004.htm Beyond-silicon technology demands ultra-high-performance field-effect transistors (FETs). Transition metal dichalcogenides (TMDs) provide an ideal material platform, but the device performances such as contact resistance, on/off ratio, and mobility are often limited by the presence of interfacial residues caused by transfer procedures. We show an ideal residue-free transfer approach using polypropylene carbonate (PPC) with a negligible residue for monolayer MoS2. By incorporating bismuth semimetal contact with atomically clean monolayer MoS2-FET on h-BN substrate, we obtain an ultralow Ohmic contact resistance approaching the quantum limit and a record-high on/off ratio of ~1011 at 15 K. Such an ultraclean fabrication approach could be the ideal platform for high-performance electrical devices using large-area semiconducting TMDs.

Mon, 31 Jul 2023 13:28:32 EDT //www.koonmotors.com/releases/2023/07/230731132832.htm When electrons slowly vanish during cooling //www.koonmotors.com/releases/2023/07/230731110743.htm Many substances change their properties when they are cooled below a certain critical temperature. Such a phase transition occurs, for example, when water freezes. However, in certain metals there are phase transitions that do not exist in the macrocosm. They arise because of the special laws of quantum mechanics that apply in the realm of nature's smallest building blocks. It is thought that the concept of electrons as carriers of quantized electric charge no longer applies near these exotic phase transitions. Researchers have now found a way to prove this directly. Their findings allow new insights into the exotic world of quantum physics.
