Chiral electrons and spin selectivity at chiral-achiral interfaces
Xiaoming Wang, Yeming Xian, Yanfa Yan
Chiral molecules can selectively transport electrons of a particular spin orientation, yet the underlying mechanism remain poorly understood. Here, we present theoretical evidence…
Subsurface Characteristics of Metal-Halide Perovskites Polished by Argon Ion Beam
Yu-Lin Hsu, Chongwen Li, Andrew C. Jones +4
Focused ion beam (FIB) techniques have been frequently used to section metal-halide perovskites for microstructural investigations. However, the ion beams directly irradiated to th…
Optical Activity of Solids from First Principles
Xiaoming Wang, Yanfa Yan
Within the framework of independent particle approximation, the optical activity tensor of solids is formulated as from different contributions: the magnetic dipole, electric quadr…
Molecular engineering of metal-free perovskite MDABCO-NH4I3 towards enhanced ferroelectric polarization
Xiaoming Wang, Yanfa Yan
Molecular ferroelectrics have attracted increasing interests over the past decade due to mechanical flexibility, chemical diversity, environmental friendliness, easy-processing, an…
Superior Photo-carrier Diffusion Dynamics in Organic-inorganic Hybrid Perovskites Revealed by Spatiotemporal Conductivity Imaging
Xuejian Ma, Fei Zhang, Zhaodong Chu +9
The outstanding performance of organic-inorganic metal trihalide solar cells benefits from the exceptional photo-physical properties of both electrons and holes in the material. He…
Coherent Band-Edge Oscillations and Dynamic LO Phonon Mode Splitting as Evidence for Polaronic Coupling in Perovskites
Z. Liu, C. Vaswani, L. Luo +12
The coherence of collective modes, such as phonons, and their modulation of the electronic states are long sought in complex systems, which is a cross-cutting issue in photovoltaic…
