Abstract
The effect of band renormalization and dynamic screening in near band edge femtosecond optical probing of In0.53Ga0.47As thin films has been investigated quantitatively. Simulated results, obtained from an ense mble Monte Carlo formulation, are in excellent agreement with measured equal pulse correlation data only if both processes are included. Ban d renormalization is found to be roughly twice as important as dynamic screening for these conditions.
