Abstract
This chapter goes into the physics behind Ti0.43Sb2Te3-based PCM in more depth to explain the high performances. Through Cs-corrected TEM, Ti atoms in Ti0.43Sb2Te3 alloy are observed evidently to substitute part of Sb atoms in the quintuple atomic layers (…Te-Sb (Ti)-Te-Sb-Te…), forming six bonds with adjacent Te atoms. These Ti-centered octahedral local structures are just slightly distorted after amorphization, which may be responsible for the significantly improved performances.
