Journal ArticleDOI
Pressure-Induced Emission (PIE) and Phase Transition of a Two-dimensional Halide Double Perovskite (BA) 4 AgBiBr 8 (BA=CH 3 (CH 2 ) 3 NH 3 + )
Yuanyuan Fang,Long Zhang,Lianwei Wu,Jiejuan Yan,Jiejuan Yan,Yu Lin,Kai Wang,Kai Wang,Kai Wang,Wendy L. Mao,Wendy L. Mao,Bo Zou +11 more
TL;DR: Analysis of combined in situ high-pressure photolu-minescence, absorption, and angle-dispersive X-ray diffraction data indicates that the observed PIE can be attributed to the emission from self-trapped excitons.
Journal ArticleDOI
Tuning Emission and Electron–Phonon Coupling in Lead-Free Halide Double Perovskite Cs2AgBiCl6 under Pressure
Long Zhang,Yuanyuan Fang,Laizhi Sui,Jiejuan Yan,Kai Wang,Kai Wang,Kaijun Yuan,Wendy L. Mao,Wendy L. Mao,Bo Zou +9 more
TL;DR: Lead-free halide double perovskites have been proposed as candidates to replace Pb-halide perovsites in photovoltaic and optoelectronic applications due to their enhanced stability and nontoxicity as mentioned in this paper.
Journal ArticleDOI
Preserving a robust CsPbI3 perovskite phase via pressure-directed octahedral tilt.

TL;DR: In this article, a black CsPbI3 perovskite structure was demonstrated to be stable at room temperature by subjecting the δ phase to pressures of 0.1 -0.6 GPa followed by heating and rapid cooling.
Journal ArticleDOI
Large bandgap of pressurized trilayer graphene.
Feng Ke,Yabin Chen,Ketao Yin,Jiejuan Yan,Hengzhong Zhang,Zhenxian Liu,John S. Tse,Junqiao Wu,Ho-kwang Mao,Bin Chen +9 more
TL;DR: A microwiring technique for high-pressure electrical measurement on nanomaterials with only a few layers is developed and it is demonstrated that an intrinsic bandgap of 2.5 eV is achievable in compressed Bernal-stacked trilayer graphene.
Journal ArticleDOI
Stability and Compressibility of Cation-Doped High-Entropy Oxide MgCoNiCuZnO5
Jian Chen,Weixin Liu,Junxiu Liu,Xiaoliang Zhang,Mingzhi Yuan,Yunlei Zhao,Jiejuan Yan,Mingqiang Hou,Jinyuan Yan,Martin Kunz,Nobumichi Tamura,Hengzhong Zhang,Zhoulan Yin +12 more
TL;DR: High-entropy oxides (HEOx) are multicomponent (≥5) complex oxides that possess material properties and functions unexpected from their constituent simple oxides.
