Electronic Transport and Thermopower in

In this review, we discuss the impact of interfaces and heterojunctions on the electronic and thermoelectric transport properties of materials. Our objective is to synthesize recent progress in understanding electronic transport in two-dimensional (2D) materials such as graphene and transition metal dichalcogenides (TMDs), exploring various forms including homo- and lateral heterojunctions, as well as vertical van der Waals (vdW) heterostructures. We analyze recent advances in thermopower within 2D heterojunctions and their device applications, particularly in resonant tunneling diodes (RTDs). Furthermore, the review extends to three-dimensional (3D) heterostructures, summarizing the current state of research on quantum effects in transport facilitated by Wigner and non-equilibrium Green's functions (NEGF) methodologies. Our findings indicate significant advancements in both simulation techniques and experimental practices that enhance the understanding of transport phenomena in heterostructures. This growing knowledge base is poised to facilitate breakthroughs in energy conversion technologies and the development of next-generation quantum nanoelectronic devices.
