A new digital approach to PICTS technique was applied to study deep le
vels in undoped SI GaAs and Fe-doped InP. For SI Fe-doped InP, the 0.6
4-eV trap related to Fe2+/Fe3+ acceptor level as well as the 0.53-eV t
rap attributed to a native defect, were observed. For SI undoped GaAs,
three traps: T1 (0.58 eV), T2 (0.66 eV) and T3 (0.73 eV) assigned to
the known centers EL3, HL9, and EL2, respectively, were resolved. The
studies were completed by the electron spin resonance (ESR) measuremen
ts.
