Abstract

Hybrid Halide Perovskites

In article number 2414437, Lingping Kong, Jue Gong, Mercouri G. Kanatzidis, Gang Liu, and co-workers unveil a behavior evolution pattern of the physical properties of hybrid perovskites under hydrostatic compression. This general pattern is applicable to both lead-based and tin-based perovskites assuming 3D and 2D crystal structures. By using the general pattern as an instructional guide and choosing appropriate peak pressures, large bandgap tunability and sensitivity are discovered along with irreversible defect healing and PL enhancement in the tin-based 2D perovskites after pressure treatment.

揭示混合卤化物包光体的普遍压力驱动行为以及极软二维锡基体系的独特光学可调性（Adv.）

混合卤化物包晶石在文章编号 2414437 中，孔令平、龚珏、Mercouri G. Kanatzidis、刘刚及其合作者揭示了混合包晶石在静水压作用下物理性质的行为演化模式。这种一般模式适用于假设三维和二维晶体结构的铅基和锡基包晶石。通过使用该一般模式作为指导，并选择适当的峰值压力，我们发现锡基二维包光体在经过压力处理后具有较大的带隙可调性和灵敏度，同时还具有不可逆的缺陷愈合和聚光增强。
