Abstract:
This dissertation addresses two research problems under the general heading of electron and phonon effects on the optical properties of indirect gap semiconductors. The first problem concerns the optical characteristics of ion-bombarded diamond crystals. This study employs coherent acoustic phonon interferometry, an ultrafast optical technique, to measure the implantation-induced optical modification. The second problem addresses nonlinear multiphotonabsorption in germanium crystals using optical transmission, and explores the effects of electron dynamics on those measurements. In each case, the experimental results are illuminated by simulation codes.
