Abstract: Quasiparticles in semiconductors reveal different regimes of propagation. Here we theoretically analyze phonon-assisted transport of excited quasiparticles in two-dimensional systems by means of a quasi-classical kinetic equation in the presence of relaxation and local uniform force… read more here.
