摘要：
New Ga doped GeSb based phase-change materials are investigated. These materials possess good optical contrast at short wavelengths. Crystallization temperature increasing and grain size refinement are obtained by addition of Ga. More than 50 dB CNR and 25 dB erasability are measured in disks with simple four layer stacks using blue laser and linear velocities 7 m/s and 10.5 m/s.
