摘要:
Simultaneous infrared transmission and laser light scattering experiments on GaAs grown by the liquid encapsulated Czochralski technique are reported. Low‐temperature photoquenching experiments are employed to demonstrate in a direct way that the nonuniform infrared images of large diameter GaAs crystals arise from absorption rather than scattering processes.
