Giant spin-splitting and gap renormalization driven by trions in single-layer WS2/h-BN heterostructures

In two-dimensional (2D) semiconducting transition metal dichalcogenides (TMDs), new electronic phenomena such as tunable bandgaps 1 – 3 and strongly bound excitons and trions emerge from strong many-body effects 4 – 6 , beyond the spin and valley degrees of freedom induced by spin–orbit coupling and...
