  author={Sangkha Borah and Dinesh Yadav and Maxim Trushin and Fabian Pauly},
Being used in optoelectronic devices as ultra-thin conductor-insulator junctions, detailed investiga-tions are needed about how exactly h -BN and graphene hybridize. Here, we present a comprehensive ab initio study of hot carrier dynamics governed by electron-phonon scattering at the h -BN/graphene interface, using graphite (bulk), monolayer and bilayer graphene as benchmark materials. In contrast to monolayer graphene, all multilayer structures possess low-energy optical phonon modes that…

Tunable Ultrafast Thermal Relaxation in Graphene Measured by Continuous-Wave Photomixing.

A novel photocurrent spectroscopy method that uses the mixing of continuous-wave lasers in a graphene photothermal detector to measure the frequency dependence and nonlinearity of hot-electron cooling in graphene as a function of the carrier concentration and temperature reveals that near the charge neutral point the nonlinear power dependence of the electron cooling is dominated by disorder-assisted collisions.
