Abstract:
Femtosecond dynamics of 5.00-THz coherent longitudinal optical phonons in CdTe is reported. Polarization dependence indicates that, as in III–V semiconductors, field screening in the depletion layer is the main generation mechanism. The amplitude of the coherent phonons shows saturation with increasing photoexcitation density. This counterintuitive behavior is interpreted as saturation in the screening of surface potential.
