Enhanced Thermoelectric Power Factor in Carrier‐Type‐Controlled Platinum Diselenide Nanosheets by Molecular Charge‐Transfer Doping (Small 23/2022)

Year: 2022

Type: article

Abstract: Molecular Charge-Transfer Doping N- and p-type thermoelectric transports are obtained by solution-depositing strong molecular reductant (benzyl viologen) and oxidant (magic blue), respectively, based on the same parental PtSe2 crystal. The synergetic effects of the tuning of the band overlap by controlling the thickness of the 2D transition metal dichalcogenides, and the introduction of dopants to the materials through molecular surface charge transfer doping, provide beneficial insights for the development of facile routes for the design of highly efficient thermoelectric energy conversion systems based on 2D nanomaterials.
