- Summary
- Transport measurements have been carried out on Al/sub x/Ga/sub 1-x/As with x less than or equal to 0.3 and the results compared with theory. In addition, measurements of transient capacitance have been used to investigate GaAs p-n homojunctions and GaAs/Al/sub 0.2/Ga/sub 0.8/As heterojunctions. Activation energies of dominant electron traps and their cross section have been calculated and the variations in emission rate for electron traps in the heterostructure has been obtained. The results of this study together with measurements on photoluminescence, which allows determination of the excitonic spectra and binding energies of impurity and defect levels as a function of x, are the subject of a scientific paper soon to be submitted for technical publication.
