Abstract
The optical-absorption spectra of AlAs and AlP exhibit unusual features—strong Al 2p core-excitonic lines. The data were obtained with synchrotron-radiation photoemission in the partial-yield mode. The analysis was based on the approach proposed by Johnson, Fock, Ley, and Cardona for AlSb and on Onodera and Toyozawa’s exciton theory.Keywords
