Research Abstract

In recording process of optical disks and phase change memory(PCM) devices, chalcogenide material was molten and quenched at recording process by a laser light or Jule heating. The solid state properties at molting phase is needed in order to clarification of the recording process, however, it has not been enough to study the properties at the molting states. In this project, the techniques and equipments for the measurements of refractive indices, electric resistivity and thermal conductivity in melting state were developed, then the development of equipments for the in-situ observation of crystallinity optical disks and PCM and the development of ultra low electric power consumption optical switch element produced by chalcogenide material are also reported.
