Understanding structural variations in elastic organic crystals by in situ high-pressure Fourier transform infrared spectroscopy and nanoindentation study by Ganguly, Somnath, Chinnasamy, Ragaverthini, Parikh, Shyamal, Kiran, Mangalampalli S. R. N., Ramamurty, Upadrasta, Bhatt, Himal, Deo, Mukul Narayan, Ghosh, Soumyajit, Ghalsasi, Pallavi

“…The infrared stretching wavenumber of the aromatic and aliphatic C-H, H-C=N, and C-Cl bands on compression showed blueshifts and increased widths, which reflect structure perturbation caused by changes in intermolecular interactions in the crystals. It was noted that both crystals DPA and DFA behave in a different fashion under high-pressure prompting the derivation of different models based on structural changes in the lattice. …”

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

“…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.

“…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. …”

Controlled synthesis of cubic and hexagonal phase lanthanide doped NaYF4 up-converters by Ho, John Chun Wan.

“…Co-precipitation using sodium fluoride (NaF) and yttrium, ytterbium and erbium nitrates in presence of disodium ethylenediaminetetraacetic acid (Na2-EDTA) was deployed to synthesize cubic NaYF4:Yb,Er nanocrystals followed by annealing to enable the cubic to hexagonal phase transition at high temperature. Hexagonal with trace amounts of cubic NaYF4:Yb,Er crystals with narrow size distribution are produced. …”
