  • Nominated as an outstanding thesis by the University of Chinese Academy of Sciences

  • Proposes a novel Ti-Sb-Te alloy for high-speed and low-power phase change memory

  • Covers both the mechanism and component optimizations of the Ti-Sb-Te alloy, as well as its applications in phase-change memory chips


Part of the Springer Theses book series (Springer Theses)

About this book


This book introduces a novel Ti-Sb-Te alloy for high-speed and low-power phase-change memory applications, which demonstrates a phase-change mechanism that differs significantly from that of conventional Ge2Sb2Te5 and yields favorable overall performance. Systematic methods, combined with better material characteristics, are used to optimize the material components and device performance. Subsequently, a phase-change memory chip based on the optimized component is successfully fabricated using 40-nm complementary metal-oxide semiconductor technology, which offers a number of advantages in many embedded applications.

About the authors

Min Zhu received his B.Sc. in Electronics Science and Technology from Hubei University, China in 2009, and completed his Ph.D. in Microelectronics and Solid-State Electronics at Shanghai Institute of Microsystem and Information Technology, Chinese Academy of Sciences in 2014. His major research project in Prof. Zhitang Song’s group concerned a Ti-Sb-Te alloy for high-speed and low-power phase change memory. Subsequently, he received an Alexander von Humboldt Research Fellowship and became a post-doctoral fellow working with Prof. Matthias Wuttig at RWTH Aachen University, investigating the crystallization behavior of phase change materials.
