摘要：

A diffusion time-of-flight (TOF) technique is described and analysis is performed on four different p-GaAs heterostructure devices. These p/n junction devices were grown by metal organic chemical vapor deposition (MOCVD). Both Zn and Mg were used as dopants with concentrations ranging from 1X1018 to 1 × 1019 cm −3. We have been able to determine the diffusivity (D) along with upper and lower estimates of the diffusion length (LD). The results imply the presence of a mechanism such as photon recycling. © 1990, American Vacuum Society. All rights reserved.
