Persistent photoconductivity in a-IGZO thin films induced by trapped electrons and metastable donors
Amorphous In-Ga-Zn-O (a-IGZO) thin films are prepared by pulsed laser deposition and fabricated into thin film transistors (TFTs). The concentration of oxygen vacancies in a-IGZO thin films is determined by the deposition oxygen pressure, as characterized by in situ x-ray photoelectron spectroscopy....
