Coexisting Large and Small Polarons in Photoexcited CeO
Valentina Mazzotti, Eleonora Spurio, Nicolas Delnour +5
Time-resolved terahertz (THz) spectroscopy is used to probe polaron formation in CeO. The ultrafast THz photoconductivity is dominated by contributions from large hole and smal…
Simulation of mechanical effects of hydrogen in bicrystalline Cu using DFT and bond order potentials
Vasileios Fotopoulos, Alexander L. Shluger
Hydrogen embrittlement is a prime cause of several degradation effects in metals. Since grain boundaries (GBs) act efficiently as sinks for hydrogen atoms, H is thought to segregat…
Substitutional tin acceptor states in black phosphorus
Mark Wentink, Julian Gaberle, Martik Aghajanian +6
Nominally-pure black phosphorus (BP) is commonly found to be a p-type semiconductor, suggesting the ubiquitious presence of impurity species or intrinsic, charged defects. Moreover…
Disorder-induced electron and hole trapping in amorphous TiO2
David Mora-Fonz, Moloud Kaviani, Alexander L. Shluger
Thin films of amorphous (a)-TiO2 are ubiquitous as photocatalysts, protective coatings, photoanodes and in memory application, where they are exposed to excess electrons and holes.…
The origin of negative charging in amorphous AlO films: The role of native defects
Oliver A. Dicks, Jonathon Cottom, Alexander L. Shluger +1
Amorphous aluminum oxide AlO (a-AlO) layers grown by various deposition techniques contain a significant density of negative charges. In spite of several experiment…
Mechanism of phase transitions and the electronic density of states in (La,Sm)FeAsOF from ab initio calculations
P. V. Sushko, A. L. Shluger, M. Hirano +1
The structure and electronic density of states in layered LnFeAsOF (Ln=La,Sm; =0.0, 0.125, 0.25) are investigated using density functional theory. For the =0.0 sy…
