Abstract

The determination of Au-based Te alloys suitability as phase change recording alloys for optical data storage was discussed. Au₁₈Sb ₂₃Te₅₉ was identified as a suitable phase change material with a recrystallization time of 110 ns and high optical contrast. The crystallization for Au₁₈Sb₂₃Te₅₉ and Au ₁₉In₂₆Te₅₅ was accompanied by a change of at least two orders of magnitude in sheet resistance. Results show that suitable phase change alloys possessed cubic structures for sp³ bonded semiconductors.
