In article number 1907364, Can Ataca, Sefaattin Tongay, and co‐workers apply high pressures to a variety of different kinds of 2D halide perovskites in a diamond anvil cell. The results reveal unusual phase transitions and changes in materials properties that are closely tied to the chemistry of the 2D perovskite layers. This study gives unique insights into such pressure‐induced changes and extends the understanding of these highly anisotropic layered soft organic perovskite materials under extreme conditions.

层状钙钛矿：二维vdW混合卤化钙钛矿中异常的压力驱动相变和能带归一化（Adv。Mater。12/2020）

在编号1907364中，Can Ataca，Sefaattin Tongay及其同事对钻石砧室中的各种2D卤化物钙钛矿施加了高压。结果表明，与2D钙钛矿层的化学性质密切相关的异常相变和材料性能变化。这项研究为这种压力引起的变化提供了独特的见解，并扩展了在极端条件下对这些高度各向异性的层状柔软有机钙钛矿材料的理解。
