摘要: We model equilibrium properties of possible room-temperature electron-hole exciton condensates formed between two dielectrically separated transition metal dichalcogenide (TMD) layers, MoS 2 layers here, toward application to novel beyond CMOS devices. Our simulation method employs an interlayer Fock exchange interaction incorporated into otherwise intra-layer tight-binding Hamiltonian within a maximally-localized Wannier function (MLWF) basis set.
