“…GaAs/Ge heterostructures are ®nding applications in space under conditions of low intensity and low illumination, such as the Mars path®nder mission and Rosetta, where the solar cells experience a very low temperature [5]. In geo-stationary orbit satellite applications, the solar cells experience a temperature of about 93 K for a short time [6], when the satellite is coming out of the eclipse.…”

The current±voltage characteristics of Au/n-GaAs Schottky diodes grown by metal-organic vapor-phase epitaxy on Ge substrates were determined in the temperature range 80±300 K. The zero-bias barrier height for current transport decreases and the ideality factor increases at low temperatures. The ideality factor was found to show the T 0 eect and a higher characteristic energy. The excellent matching between the homogeneous barrier height and the eective barrier height was observed and infer good quality of the GaAs ®lm. No generation±recombination current due to deep levels arising during the GaAs/Ge heteroepitaxy was observed in this study. The value of the Richardson constant was found to be 7.04 A K À2 cm À2 , which is close to the value used for the determination of the zero-bias barrier height. Ó
