Abstract

IR imaging (2D radiation mapping) of forward biased point contact LEDs based on p-InAsSbP/n-InAs/n-InAsSbP DHs and p-InAsSbP/n-InAs SHs revealed differences in current crowding effect that was attributed to the properties of isotype n-InAsSbP/n-InAs barrier. 2D radiation distribution has been used for determination of L-I and I-V characteristics that are not distorted by the current crowding. The existence of the n-InAsSbP/n-InAs barrier was also traced in AFM and C-V measurements.
