In a new report now published on Science Advances, Tiancheng Song and a research team at the department of physics, University of Washington, U.S., and materials and nanoarchitectronics in Japan and China, detailed spin photovoltaic ...
Topological insulators have notable manifestations of electronic properties. The helicity-dependent photocurrents in such devices are underpinned by spin momentum-locking of surface Dirac electrons that are weak and easily ...
2-D materials, consisting of a single layer of atoms, are revolutionizing the field of electronics and optoelectronics. They possess unique optical properties that their bulky counterparts do not, spurring the creation of ...
