Charge transfer phenomena in semi-insulating InP:Fe
Charge transfer phenomena are studied in semi-insulating InP:Fe. It is shown that the Fe-absorption is changed under exposure to near IR-light due to pumping of charge carriers into traps other than Fe. This process may affect the determination of the Fe-distribution in InP:Fe by optical absorption. From the change in Fe-absorption the absolute concentration of traps can be estimated. The spectral dependence of the charge transfer process reveals that mainly electron traps are active above 80K.<>
