Abstract:

Understanding the phonon transport in stanene is essential to predicting the thermal performance of stanene-based technologies in the future. Using a first principal calculation and the phonon Boltzmann transport equation, one may estimate stanene's thermal conductivity at its lattice level of organisation. Stanene has a substantially lower heat conductivity than other 2D materials. Analysis of the effect phonons have on lattice thermal conductivity is carried out in great depth. A three-phonon phase space study has shown, it has been shown that high-group-velocity LA phonons play a major role when it comes to the thermal conductivity. For the design of thermoelectric nanostructures, thermal conductivity is also studied in terms of its size dependency.
