【Abstract】 Abstract: By electrochemical C U measurment associated with chemical etching, the carrier concentration profiles in a batch of GaP∶N LPE samples made in China were measured. The relative luminances of the samples were also measured with electroluminescence and photoluminescence. A comparison between the two measurement results showed that, the carrier concentration in the first n type epilayer depends on the concentration of multi crystalline GaP mixed in the Ga solution, and the luminance increases with decreasing of the carrier concentration in the second n type epilayer.更多还原
