Superlattice Films
Work function difference induces spontaneous charge donation and band bending at the interfaces of superlattices, which causes optimization effects of modulation doping and energy filtering, leading to remarkably enhanced thermoelectric performances. This optimizing strategy is successfully elucidated in 1T′‐MoTe2/Bi2Te3 superlattice films. Meanwhile, the rational manipulation of...
Interfacial charge effects, such as band bending, modulation doping, and energy filtering, are critical for improving electronic transport properties of superlattice films. However, effectively manipulating interfacial band bending has proven challenging in previous studies. In this study, (1T′‐MoTe2)x(Bi2Te3)y superlattice films with symmetry‐mismatch were successfully fabricated via the molecular...
