Journal ArticleDOI
Structurally induced semimetal-to-semiconductor transition in 1T-TiSe2
TL;DR: In this paper, it was shown that the transition from the normal semimetallic state to the charge-density-wave semiconducting state can be successfully modeled by variation of a single structural parameter, which modulates the Ti-Se bond length.
Journal ArticleDOI
High-resolution structural study of Bi on Si(001)
Gillian Franklin,Shaoping Tang,Joseph C. Woicik,Michael J. Bedzyk,Michael J. Bedzyk,Arthur J Freeman,Jene Andrew Golovchenko +6 more
TL;DR: X-ray standing-wave measurements, along with first-principles local-density molecular-cluster calculations, have determined the Bi-dimer orientation, location, and bond length for the Si(001)-(1{times}2):Bi surface.
Journal ArticleDOI
Prediction of strong bonding effects and an anomalous form factor in Sc metal
Raju P. Gupta,Arthur J Freeman +1 more
TL;DR: In this article, field-induced magnetization densities of Sc metal determined from augmented plane-wave functions, including local density-of-states effects, were found to show a large spatial expansion of the 3D density and strong bonding effects.
Journal ArticleDOI
The role of Coulomb correlation in magnetic and transport properties of doped manganites: La0.5Sr0.5MnO3 and LaSr2Mn2O7
TL;DR: In this article, the results of local spin-density approximation (LSDA) and LSDA + U calculations of the electronic structure and magnetic configurations of the 50% hole-doped pseudocubic perovskite La 0.5Sr0.5MnO3 and double-layered LaSr2Mn2O7 are presented.
Journal ArticleDOI
Magnetism and superconductivity in rare-earth ternary borides
Arthur J Freeman,T. Jarlborg +1 more
TL;DR: In this paper, the authors discuss the origin of magnetism and superconductivity in rare earth rhodium borides (MRh4B4) and the Chevrel phase ternaries MxMo6S8 (with x close to 1) using the results of self-consistent LMTO energy band calculations.
