Thickness effects on thermal conductivities of black phosphorus nanosheets, which are anisotropic in the zigzag and armchair planar directions, are experimentally and theoretically investigated in the thickness range of 13 to 48 nm.
Accurate thermal conductivity measurements of nanoscale thin-films on substrate samples by non-contact SThM with finite element heat transfer modeling in transition regime and with fitting functions and analytical heat transfer modeling for fast analysis.
