摘要：

The time-dependent change in photocurrent during illumination has been studied in amorphous arsenic tritelluride (a-As2Te3), which is an amorphous chalcogenide material with a narrow optical bandgap. No photodegradation in the photocurrent is observed in this material, although photodegradation occurs in most wide-bandgap amorphous chalcogenides.
