Manipulating the Interfacial Band Bending For Enhancing the Thermoelectric Properties of 1T′‐MoTe₂/Bi₂Te₃ Superlattice Films (Small 35/2023)

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 band bending via tuning the Te/Bi flux ratio further promotes thermoelectric performances.
