Abstract
Photoconductive properties of anodic oxide films grown on β‐Ta films have been measured at room temperature as a function of incident wavelength between 1000 and 500 nm (1.2–2.5 eV). Analysis of the spectral response of photoconductivity on thick (5200 Å) and thin (800 Å) oxides indicates the presence of a defect conduction band edge energetically at 1.5 eV below the oxide conduction band.Keywords
