摘      要：Emerging Xenes,mostly group IVA and VA elemental two-dimensional(2D)materials,have small and tunable band gaps between graphene and transition metal dichalcogenides,giving versatile electrical *** their microelectronic or optoelectronic properties are being extensively explored,there remains a lack of study on Xenes uniquely advantageous thermoelectric *** review highlights state-of-the-art experimental and theoretical progress in the thermoelectric effect and devices of IVA and VA *** displaced,a.k.a.“buckledor“puckered,atomic arrays result in exotic and tunable electrical or thermal transport *** from chemical doping strategies usually employed in bulk thermoelectric materials,2D Xenes can be tuned by physical means,such as atomic layer control and quantum confinement effects.A precise and compatible platform for 2D thermoelectric effect and devices study is available via the engagement between micro/nanofabrication of 2D Xene transistors and thermal property measurement *** review also reveals potential thermoelectric applications of Xenes and their compounds(Bi2Te3,Bi2Se3,etc.),such as accurate stretchable temperature sensors,fast terahertz photodetectors,and so on.
