Sample interview questions: Can you discuss any experience you have with studying the thermal properties of nanomaterials?
Sample answer:
I possess ample experience in investigating the thermal properties of nanomaterials. My research has primarily focused on understanding the impact of size, shape, and composition on the thermal conductivity, specific heat capacity, and thermal diffusivity of various nanostructures.
One notable project involved examining the thermal transport properties of silicon nanowires. We synthesized nanowires with controlled diameters and lengths and measured their thermal conductivity using a suspended microdevice. The results revealed a strong size dependence, with smaller nanowires exhibiting lower thermal conductivity due to increased phonon scattering at the boundaries.
In another study, we explored the influence of surface functionalization on the thermal properties of graphene. By chemically modifying the graphene surface with different functional groups, we… Read full answer
