1. Time-resolved x-ray diffraction study of longitudinal optical phonons in zincblende semiconductors
University essay from Lunds universitet/Atomfysik; Lunds universitet/Fysiska institutionenAbstract : Anharmonic decay of longitudinal optical (LO) phonons in zincblende semiconductors is not at present well characterized due to the polar and many-body nature of the problem. Femtosecond THz radiation offers a novel route to this study, as the interaction of this radiation is directly with the phonon lattice and these THz excited phonons do not have enough energy to excite electrons over the band gap.
