• Using the modulated photocurrent method to measure physical properties in the highstrtrctural-ctualit.v sin:le-rhase icosahedral cttrasicr.vstalline allov Alwo.sPdxtRes.s, we observedphotocurrent similar to that in semiconductors in quasicrystals. The observed results were inagreenaent with those obtained by applying our recently developed photocondtuctivity modelused for boron-rich semiconductors in which band-to-band photoexcitation and photoexcitationfrom a band to localized states f'oI[owed by thernaal excitation to the conduction band are bothconsidered. Our results confirun the existence of a pseudogap at the Fermi energy Ep and thetendency of carriers to localize near Ev.
