The presence of photoconductivity in thin films of β-Ga2O3 and β- Ga2O3:Cr3+ obtained by radio-frequency (RF) ion-plasma sputtering after heat treatment in air has been established. The obtained photoconductivity spectra are analysed, and it is shown that the photoconductivity in pure thin β-Ga2O3 films is due to intrinsic photoconductivity because of the band–gap electronic transitions. In thin β-Ga2O3:Cr3+ films, in addition to this photoconductivity band, there are also three photoconductivity bands observed due to electronic transitions within the Cr3+ activator ion. At the same time, all three excited levels fall into the conduction band and lead to the appearance of U-, Y-, and V-bands of photoconductivity. [ABSTRACT FROM AUTHOR] |
