Electronic thermal conductivity of few-layer black phosphorus

Narayan Gaonkar,
R G Vaidya

Abstract: The theoretical investigations of anisotropic electronic thermal conductivity of nanoscale black phosphorus along zigzag and armchair directions are presented. Electrons in black phosphorus assumed to be scattered by in-plane linear dispersion phonons and out-of-plane quadratic dispersion phonons via deformation potential couplings. The individual contributions from in-plane phonon and out-of-plane phonon processes to the electronic thermal conductivity show dominant role of in-plane phonon processes. The anis… Show more

“…Recently, black phosphorus (BP), a layered material, has garnered significant attention from scholars due to its wide-ranging applications in various fields. Its ultra-high charge mobility [1][2][3][4], ultra-high band gap [5][6][7][8], excellent heat conductivity [9][10][11], remarkable in-plane anisotropic optical absorption characteristics [12,13], and special mechanical properties [14][15][16] make it suitable for use in field-effect transistors, semiconductors, thermology, optics, and mechanics, respectively. The mechanical properties are crucial for the dynamic behavior of BP.…”
