文摘

Gamma radiation response was found to differ for As2Se3 in film and bulk form. Gamma effects anneal out at room temperature over two weeks for bulk glass, while long-term effects remain in the films. A mechanism based on coordination topological defects is proposed to explain the gamma radiation responses.
