Properties of the room-temperature electron trap in rutile

Abstract

By a combination of thermoluminescence, thermally stimulated current, and photocurrent measurements, the electron trapping parameters of the room-temperature trap in rutile were obtained. The photon-capture cross section and the electron-frequency factor were determined. The values of the electron-capture cross section, the trap density, and the ratio of optical to thermal ionization energies of the trap were calculated. The relation of the trapping center to the photocurrent decay is discussed. © 1971 The American Institute of Physics.
