Evidence for pressure-induced node-pair annihilation in Cd3As2
Cheng Zhang, Jianping Sun, Fengliang Liu +12
As an intermediate state in the topological phase diagram, Dirac semimetals are of particular interest as a platform for studying topological phase transitions under external modul…
Enhanced Structural Stability and Photo Responsiveness of CH3NH3SnI3 Perovskite via Pressure-Induced Amorphization and Recrystallization
Xujie Lü, Yonggang Wang, Constantinos C. Stoumpos +10
An organic-inorganic halide perovskite of CH3NH3SnI3 with significantly improved structural stability is obtained via pressure-induced amorphization and recrystallization. In situ…
Comment on A First-order Phase Transition to Metallic Hydrogen
Alexander F. Goncharov, Zachary M. Geballe
A recent paper by Zaghoo et al. presents optical data at high-pressure and high-temperature and interprets the data as evidence for a first-order phase transition to metallic hydro…
Origin of Stationary Domain Wall Enhanced Ferroelectric Susceptibility
Shi Liu, R. E. Cohen
Ferroelectrics usually adopt a multi-domain state with domain walls separating domains with polarization axes oriented differently. It has long been recognized that domain walls ca…
Simultaneous band gap narrowing and carrier lifetime prolongation of organic-inorganic trihalide perovskites
Lingping Kong, Gang Liu, Jue Gong +12
The organic-inorganic hybrid lead trihalide perovskites have been emerging as the most attractive photovoltaic material. As regulated by Shockley-Queisser theory, a formidable mate…
Ultrafast terahertz-field-driven ionic response in ferroelectric BaTiO
F. Chen, Y. Zhu, S. Liu +31
The dynamical processes associated with electric field manipulation of the polarization in a ferroelectric remain largely unknown but fundamentally determine the speed and function…
Topological Dirac line nodes and superconductivity coexist in SnSe at high pressure
Xuliang Chen, Pengchao Lu, Xuefei Wang +15
Due to fundamental interest and potential applications in quantum computation, tremendous efforts have been invested to study topological superconductivity. However, bulk topologic…
Structural Diversity in Lithium Carbides
Yangzheng Lin, Timothy A. Strobel, R. E. Cohen
The lithium-carbon binary system possesses a broad range of chemical compounds, which exhibit fascinating chemical bonding characteristics that give rise diverse and technologicall…
Topological surface states in dense solid hydrogen
Ivan I. Naumov, Russell J. Hemley
It has recently been established that two-dimensional massless graphene-like systems and three-dimensional line-node topological semimetals comprise a special class of centrosymmet…
Caloric Effects in Methylammonium Lead Iodide from Molecular Dynamics Simulations
Shi Liu, Ronald E. Cohen
Organic-inorganic hybrid perovskite architecture could serve as a robust platform for materials design to realize functionalities beyond photovoltaic applications. We explore calor…
Hydrogen sulfide at high pressure: change in stoichiometry
Alexander F. Goncharov, Sergey Lobanov, Ivan Kruglov +5
Hydrogen-sulfide (H2S) was studied by x-ray synchrotron diffraction (XRD) and Raman spectroscopy up to 150 GPa at 180-295 K and by quantum-mechanical variable-composition evolution…
Synthesis of Polar Ordered Oxynitride Perovskite
Muhtar Ahart, Maddury Somayazulu, Rajasekarakumar Vadapoo +5
For decades, numerous attempts have been made to produce polar oxynitride perovskites, where some of the oxygen are replaced by nitrogen, but a polar ordered oxynitride has never b…
Atomistic Description for Temperature-Driven Phase Transitions in BaTiO
Yubo Qi, Shi Liu, Ilya Grinberg +1
Barium titanate (BaTiO) is a prototypical ferroelectric perovskite that undergoes the rhombohedral-orthorhombic-tetragonal-cubic phase transitions as the temperature increases.…
