Sample interview questions: Can you discuss any experience you have with studying the thermal transport in nanomaterials?
Sample answer:
As a Solid-State Physicist, I possess extensive experience in investigating thermal transport phenomena in nanomaterials. My research primarily focuses on understanding the fundamental mechanisms governing heat conduction and energy dissipation at the nanoscale.
One significant project involved studying the thermal conductivity of graphene-based nanostructures using a combination of experimental and computational techniques. I successfully fabricated graphene nanoribbons and nanoporous graphene membranes and employed time-domain thermoreflectance to measure their thermal properties. The results provided valuable insights into the effect of defects, interfaces, and lattice geometry on thermal transport in these materials.
Moreover, I have conducted research on the thermal transport properties of two-dimensional materials such as transition metal dichalcogenides (TMDs). Using Raman spectroscopy and photothermal microscopy, I investigated the thermal conductivity and phonon scattering mechanisms in these atomically thin materials. My findings revealed the strong influence of strain, doping, and substrate interactions on phonon transport and heat dissipation.
