    Sliding-mediated ferroelectric phase transition in CuInP2S6 under pressure by Zhou, Zhou, Zhang, Jun-Jie, Turner, Gemma F., Moggach, Stephen A., Lekina, Yulia, Morris, Samuel, Wang, Shun, Hu, Yiqi, Li, Qiankun, Xue, Jinshuo, Feng, Zhijian, Yan, Qingyu, Weng, Yuyan, Xu, Bin, Fang, Yong, Shen, Zexiang, Fang, Liang, Dong, Shuai, You, Lu

    Published 2024
    “…Along the transformation pathway, the displacive-instable Cu ion serves as a pivot point that regulates the interlayer interaction in response to external pressure. The rich phase diagram of CuInP2S6, which is enabled by stacking orders, sheds light on the physics of vdW ferroelectricity and opens an alternative route to tailoring long-range order in vdW layered crystals.…”

    Correlation between optical absorption redshift and carrier density in phase change materials by Ho, H. W., Song, W. D., Bai, K., Branicio, P. S., Tan, Teck L., Ji, R., Law, L. T., Ng, C. M., Lan, Wang.

    Published 2014
    “…Here, we report an optical absorption redshift map for GeTe-Sb2Te3 pseudo-binary alloys. We found that, with phase change from amorphous to crystalline, the observed redshift increases with Ge concentration along pseudo-line of compositions, which directly reflects the enhanced electron delocalization/resonant bonding and increased carrier concentrations in the respective crystal compounds. …”
