Thermal Conductivity Of Beta-Arsenene Under Biaxial Tensile Strain: A First Principle Study

A first principle study is conducted to explore the phonon thermal transport in a buckled arsenene monolayer (Beta-As) subjected to tensile strain. The results showed that the thermal conductivity first decreases with strains from 0% to 1%, then it increases with strains from 1% to 5%, and finally it decreases with strains from 5% to 9%. The maximum thermal conductivity occurs at strain of 5%, which is 1.45 times higher than that of unstrained arsenene. Phonon properties are investigated to understand the causes of this thermal response to strain.
