Research on graphene has revealed remarkable phenomena arising in the honeycomb lattice. However, the quantum spin Hall effect predicted at the K point could not be observed in graphene and other ...
Inexpensive near-to-mid infrared (IR) sources and detectors operating at room temperature (rather than cooled to low or even cryogenic temperatures) are expected to revolutionize current technologies ...
