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…
Study of RF Sputtered Antimony Alloyed Bismuth Vanadium Oxide (Sb:BiVO4) Thin Films for Enhanced Photoelectrochemical (PEC) performance from Bandgap Modulation to Thickness Optimization
Tilak Poudel, Yanfa Yan, Xunming Deng
Monoclinic scheelite bismuth vanadate (BiVO4) is a promising photoanode for water splitting yet the PEC performance is limited due to its relatively higher (2.4 eV) band gap. Here,…
Comparative Study of RF Sputtered Ba2(BiNb)O6 and Ba2Bi1.4Nb0.6 O6 thin films and Effect of Fluorine Doping in Their Photoelectrochemical (PEC) Performances
Tilak Poudel, Baicheng Weng, Corey Grice +2
Bismuth based ternary oxide photocatalysts are of considerable interest in photoelectrochemical water splitting. Yet these oxides are highly stable in different environment, their…
Controlled Preparation, Characterization, and Bandgap Modulation of RF Sputtered Antimony Vanadium Oxide (SbVO4) Thin Films
Tilak Poudel, Corey Grice, Yanfa Yan +1
In this paper, RF sputtered antimony vanadium oxide (SbVO4) thin films and its characterization are reported. High purity sputtering targets were fabricated by sintering a mixture…
Symbolic Regression Discovery of New Perovskite Catalysts with High Oxygen Evolution Reaction Activity
Baicheng Weng, Zhilong Song, Rilong Zhu +5
Symbolic regression (SR) is an emerging method for building analytical formulas to find models that best fit data sets. Here, SR was used to guide the design of new oxide perovskit…
First-Principles Understanding of the Electronic Band Structure of Copper-Antimony Halide Perovskite: The Effect of Magnetic Ordering
Xiaoming Wang, Weiwei Meng, Zewen Xiao +3
We report the understanding of the electronic band structure of perovskite through first-principles density-functional theory calculations. We find that the mos…
