摘要：

Amorphous GaAsP (a-GaAsP) films have been prepared by radiofrequency sputtering in argon. The composition in the deposited films was altered by varying the number of phosphorus pieces added to a crystalline GaAs target. The local structure and bonding configurations in the films have been investigated using extended x-ray absorption fine-structure (EXAFS) techniques. EXAFS spectra have been recorded at the K edges of each constituent element, and this has allowed us to construct a reasonably detailed picture of the local structure in the a-GaAsP films. The results of optical absorption and infrared measurements are also reported and are found to correlate well with the EXAFS measurements.
