摘要：

We have examined specimens of vitreous a-As2Se3 using transient photocurrent techniques. These techniques allowed us to probe the electronic states contained within the mobility gap of this material. Analysis of the unique transient photocurrent data reveals a structured density of states rather than a broad featureless distribution which is sometimes said to exist in this material.
