1、Multi-level storage and ultra-high speed of superlattice-like Ge50Te50/Ge8Sb92 thin film for phase-change memory application 2017

摘要:1 online resource Abstract: Superlattice-like Ge50 Te50 /Ge8 Sb92 (SLL GT/GS) thin film was systematically investigated for multi-level storage and ultra-fast switching phase-change memory application. In situ resistance measurement indicates that SLL GT/GS thin film exhibits two distinct resistance steps with elevated temperature. The thermal stability of the amorphous state and intermediate state were evaluated with the Kissinger and Arrhenius plots. The phase-structure evolution revealed that the amorphous SLL GT/GS thin film crystallized into rhombohedral Sb phase first, then the rhombohedral GeTe phase. The microstructure, layered structure, and interface stability of SLL GT/GS thin film was confirmed by using transmission electron microscopy. The transition speed of crystallization and amorphization was measured by the picosecond laser pump-probe system. The volume variation during the crystallization was obtained from x-ray reflectivity. Phase-change memory (PCM) cells based on SLL GT/GS thin film were fabricated to verify the multi-level switching under an electrical pulse as short as 30 ns. These results illustrate that the SLL GT/GS thin film has great potentiality in high-density and high-speed PCM applications.

2、Chinese Animation, Creative Industries and Digital Culture 2017/8/17

摘要:This book explores the development of the Chinese animation film industry from the beginning of China’s reform process up to the present. It discusses above all the relationship between the communist state’s policies to stimulate "creative industries", concepts of creativity and aesthetics, and the creation and maintenance , through changing circumstances, of a "national style" by Chinese animators. The book also examines the relationship between Chinese animation, changing technologies including the rise first of television and then of digital media, and youth culture, demonstrating the importance of Chinese animation in Chinese youth culture in the digital age.
