| 英文摘要 |
Within the frame of Huang-Rhys's lattice relaxation model, we theoretically
investigate the carrier relaxation mediated by two-phonon processes, which consists
in polar surface optical phonon and longitudinal acoustic phonon emission between
the Landau levels of graphene on different polar substrates. This two-phonon
relaxation process is very fast within the picosecond scale and may seriously hinder
the carrier multiplication based on effective Auger processes. Moreover, the
polarizability of the polar substrate plays an important role in determining the
relaxation time. These results could be helpful in designing graphene-based
photoelectric and photodetector devices. Copyright (C) EPLA, 2014 |
