  • Abstract
    Preliminary results indicate that asymmetries present in the electrooptic sampling data may correspond to defect clusters created in the Ohmic contact process region and also possibly due to the crystal defect regions present in the bulk GaAs wafer. Thus it may be possible to correlate defects produced in the contact process with their related local electrical perturbations. These results are in agreement with earlier results
