Abstract:
Screening of the intrinsic piezoelectric fields in hexagonal, strained layer CdS/CdSe type II superlattices by optically generated electron-hole pairs leads to a shift of the optical transitions of up to 400meV. After intense picosecond excitation, the transition energy follows a logarithmic law as a function of time. This temporal behavior is consistent with model calculations of the density dependent transition-matrix elements in the tilted bandstructure.
