摘要

Results are given for a complex study of thin Nb2O5 films deposited in vacuum (p = 2.2 Pa) on quartz and silicon substrates using multi-pulse high-frequency laser action (f ~ 10–12 kHz) on a ceramic target with laser power density q = 81 MW/cm2. The morphology of these films was studied using atomic force microscopy. Features of the transmission spectra were presented. The photoelectrical properties of the Nb2O5/Si structure were analyzed.
