Photoconductivity Effects in Air-Induced and Fluorofullerene-Induced Surface Conducting Diamond
The photoelectrical properties of the hydrogen-terminated diamond surface in the presence of surface conducting
layer has not been reported in the literature. This paper presents the preliminary study on the photoelectrical behaviour of the
air-induced and fluorofullerene-induced surface conducting diamond. The photoconductivity observed is attributed to the
excitation of electrons from the near-surface valence band into trap states, giving rise to a higher sub-surface hole current
while the persistent photocurrent decay suggests the role of charge trapping at the trap states.
