19 January 1984 Photodiode Quantum Efficiency Improvement through Vacuum Surface Effects
Author Affiliations +
Surface effects stemming simply from photodiode operation in vacuum environment are seen to improve quantum efficiency significantly. This is attributed to desorption of surface impurities and consequent reduction of surface potential, recombination, and Debye length. Effective depletion layer width can also be noticeably affected by free charge redistribution after desorption of surface impurities. Quantum efficiency here in vacuum is greatest at longer wavelengths because of decreased surface depth in vacuum.
