The optical characteristics of Sb2Se3 and Sb2Te3 films are changed due to an amorphous-crystalline phase transition below 200 °C. The respective reflectivity of 400 Å Sb2Se3 and 300 Å Sb2Te3 films, each on a Te reflective layer, is increased from 10% to 30% and from 45% to 65% by laser radiation. Using these new materials, optical disc recording of FM video signals by a diode laser has been demonstrated.
Previous work has established that the optical characteristics of Sb2Se3 films are influenced by an amorphous-crystalline transition at 170 °C. This paper comments on the change in optical characteristics in an optical recording material composed of Sb2Se3 and Bi2Te3 layers caused by alloying between the layers above 250 °C.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
