• A theoretical study of the electron-phonon interaction and anisotropic carriermobilities in black phosphorus is presented. It is shown that the electron-phonon in-teraction is expressed in a deformation potential form in the rigid ion model and thelong wave phonon approach. The deformation potential constants are calculated us-ing the pseudopotential band theory and the lattice dynamical theory. The pressurecoefficient of the energy gap estimated with the deformation potential constants isfound to be in good agreement with experiment. The electron and hole mobilities areobtained by solving the Boltzmann equation. The results can explain the peculiaranisotropy of the hole and electron mobilities. Calculated mobilities at 100 K are7a ) = 1 0 . 0 , p ') = 3 . 2 , p f = 2 . 7 , p $ = 5 . 8 , p $ = 3 . 1 , and p ': = 2 . 6 X 1 0' cm' / V - s and the cor-responding observed values are 10.0, 4.0, 1.5, 6.5, 1.3, and 1.1 x 10' cm'/ V-s, respec-tively.[blackforma- l3 lionpressure ll rnefFmrientlphosphorus, annsotropic mobility, electron-phonon interactuon, defpotential, rugud ion model, long-wave phonon, band theory,Ilnltvmnnn ent?nfinn
