Coulometric determination of arsenic in gallium arsenide crystal wafers
The determination of small variations in the stoichiometry of undoped, semi-insulating gallium arsenide can be achieved by using constant current coulometry. Samples taken from a wafer are etched in HF, dissolved in NaOH-peroxide solution, then treated [...]
You can buy single crystal AlN substrate with higher photoelectric conversion efficiency than indirect band gap semiconductors from PAM-XIAMEN. Aluminum nitride (AlN) is an important blue and ultraviolet light-emitting material, which is used in ultraviolet/deep ultraviolet light-emitting diodes, ultraviolet laser diodes, and ultraviolet detectors.
