Band alignment and directional stability in abrupt and polar-compensated Si/ZnS interface calculations
David H. Foster, Guenter Schneider
We perform a first principles investigation of Si/ZnS interface properties for the [111], [100], and [110] directions, including single-substitution polar-compensated interfaces. T…
Multiscale modeling of solar cells with interface phenomena
David H. Foster, Timothy Costa, Malgorzata Peszynska +1
We describe a mathematical model for heterojunctions in semiconductors which can be used, e.g., for modeling higher efficiency solar cells. The continuum model involves well-known…
Shell Model of BaTiO3 Derived from Ab-initio Total Energy Calculations
Jason M Vielma, Guenter Schneider
A shell model for ferroelectric perovskites fitted to results of first-principles density functional theory (DFT) calculations is strongly affected by approximations made in the ex…
Defect physics and electronic properties of Cu3PSe4 from first principles
D. H. Foster, F. L. Barras, J. M. Vielma +1
The p-type semiconductor Cu3PSe4 has recently been established to have a direct bandgap of 1.4 eV and an optical absorption spectrum similar to GaAs [Applied Physics Letters, 99, 1…
Defect physics of BaCuChF (Ch=S, Se, Te) p-type transparent conductors
A. Zakutayev, J. Tate, G. Schneider
Native point defects, defect complexes, and oxygen impurities in BaCuChF were studied using density functional theory calculations, self-consistent thermodynamic simulations, and v…
Conductance of correlated systems: real-time dynamics in finite systems
Alexander Branschädel, Guenter Schneider, Peter Schmitteckert
Numerical time evolution of transport states using time dependent Density Matrix Renormalization Group (td-DMRG) methods has turned out to be a powerful tool to calculate the linea…
