Optical tuning of electronic valleys

MPSD Seminar
Monolayer transition-metal dichalcogenides such as MoS₂ and WS₂ are prime examples of atomically thin semiconducting crystals that exhibit remarkable electronic properties. They have a pair of valleys that can serve as a new degree of freedom, but these valleys are energetically degenerate, protected by time-reversal symmetry. [mehr]
