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. More information can be found in article number 2200818 by Keehoon Kang, Wooyoung Lee, and co-workers.
