A narrow enough ribbon will transform a conductor into a semiconductor. Using graphene ribbons of unimaginably small widths – just several atoms across – a group of researchers at the University of Wisconsin-Milwaukee (UWM) has found a novel way to … Continue Reading »
Physicists at UWM identify new method to “tune” graphene
Topological insulators (TI) are three-dimensional materials that conduct electricity on their surfaces, while the interior insulates. Research into a recently discovered class of materials shows they have the necessary characteristics to develop ultra-energy efficient electronics. Their surfaces are particularly unique … Continue Reading »
Physics groups at UWM publish paper on graphene interfaced with a semiconductor
Two UWM Condensed Matter Physics groups, led by Dr. Lian Li and Dr. Michael Weinert, recently published a paper on the electron transport characteristics of graphene on semiconductor surfaces. The study was published in the Nov. 21 issue of Nature … Continue Reading »
