Weakly Trapped, Charged, and Free Excitons in Single-Layer MoS2 in the Presence of Defects, Strain, and Charged Impurities
Sudipta Dubey, Simone Lisi, Goutham Nayak +17
Few- and single-layer MoS2 host substantial densities of defects. They are thought to influence the doping level, the crystal structure, and the binding of electron-hole pairs. We…

Electronic spectrum of twisted graphene layers under heterostrain
L. Huder, A. Artaud, T. Le Quang +5
We demonstrate that stacking layered materials allows a novel type of strain engineering where each layer is strained independently, which we call heterostrain. We combine detailed…
