Quantization of 'surface Dirac states' could lead to exotic applications
Tokyo, Japan (SPX) Apr 16, 2015 - Researchers from the RIKEN Center for Emergent Matter Science in Japan have uncovered the first evidence of an unusual quantum phenomenon--the integer quantum Hall effect--in a new type of film, called a 3D topological insulator. In doing this, they demonstrated that "surface Dirac states"--a particular form of massless electrons--are quantized in these materials, meaning that they only ta ... more
