Its effect on the luminescence intensity has been measured. ( 2 ) Deep levels in InP. Feng Yougang et a/. 54eV broad band in the DLTS spectrum. 40eV) have been found to exist at relatively low concentrations, in general agreement with the observation of Wada et al. (1980). (3) Deep levels in GaAlAs. In addition to the DX center observed by Lang and Logan (1979) in n-type Te-doped GaAlAs, Zhang Yunsan and Gao Jilin (1983) of IS have reported the existence of another deep center in the vicinity of DX but entirely different from DX in physical properties.

59. 2 K by Xu Jungying et al. (1984) of IS. It is found from their experimental results that the alloy composition at which N-Zn transition changes over to N bound excitonic recombinations depends on the nitrogen and zinc impurity concentrations. b. Characterization by Electrochemical Methods The electrochemical method is especially suitable for determining the concentration profile in p-n junctions and heterojunctions. This method used in conjunction with ion implantation and ion milling techniques has been applied to determine the carrier concentration and mobility profiles in submillimeter doped InP and GaAs layers by Shao Yongfu el al.

P. 296. 22 Rare Metals (in Chinese), 5 , no. 1, p. 9. 2o 1. 111-V COMPOUNDS 35 Wang Jianqiang et al. (1985)’’ of IS have observed a decrease in EL2 concentration in VPE GaAs grown under an Ar ambient compared with those grown in a Hz or N2 atmosphere. This finding is parallel to the effect of ambient gas on [EL21 in LEC GaAs found by Emori et al. (1984)24and might, in our opinion, result from the relatively low dislocation density in the Ar-grown material. An experimental confirmation of this point would be desirable.
