Investigation of pulsed semiconducting light-emitting diodes and their use in cosmic ray research equipment
Abstract
Fabrication techniques for pulsed semiconducting light-emitting diodes (LED) and calibration of LED performance characteristics are discussed, for LEDs used as sources of very short light bursts in in-flight calibration, time adjustments, and periodic checkout of cosmic ray research equipment installed on satellites, deep-space probes, and space stations. Alloying, diffusion, and epitaxial growth techniques in the fabrication of GaP and SiC LEDs are discussed. Characteristics of light burst amplitude vs current and how they are affected by defects such as trapping centers, and the brightness and relaxation characteristics of SiC, are studied.
