Abstract

Electronic properties of polycrystalline diamond films have been analysed using steady-state photoconductivity under UV (λ = 190 nm) and red (λ = 633 nm) illumination. We look at the effect of several post-deposition treatments: Annealing in vacuum at 400°C, successive annealing under air and methane or the reverse, and X-ray exposure. These are shown to affect the photoresponses in different manners. Globally, the mobility-lifetime products of samples are found in the range 10^-7-10^-6 cm² V^-1 under UV illumination, and ratios of photoresponses in UV and red are in the range 10³-10⁵. First results obtained using the modulated photocurrent technique are also presented.
