The internship explores heat and charge transport in nanostructured graphene to improve thermoelectric conversion and explore thermal rectification. Using geometrically modified graphene with periodic nano-holes or nanocostriction, it aims to control phonon and electron mean free paths, enabling asymmetric heat conduction and enhanced Seebeck effect. The student will fabricate devices (graphene transfer, e-beam lithography, etching), measure electrical and thermal properties (Seebeck coefficient, electrical and thermal conductivity, rectification), and analyze results through finite element simulations. The project offers practical training in 2D materials and advances understanding of geometry-driven thermal and thermoelectric control.
