The surface of the AlGaN barrier layer in AlGaN/GaN high electron mobility transistors has strong and hitherto unexplained effects on transistor characteristics. Indeed, it has been cited as the source of the two-dimensional electron gas at the AlGaN/ . . .

We have applied two methods to investigate the origin in the electronic structure of the unusual magnetic behavior of the uranium monochalcogenides and monopnictides. First, we have carried out spin-polarized electronic structure calculations based on . . .

The dependence of electron density (ns) on AlGaN barrier thickness (dAlGaN) was studied for AlGaN/GaN single heterostructures whose dAlGaN was controlled by low-power Cl-based reactive ion etching (RIE) instead of growth. The samples showed a constant . . .

We present a comprehensive investigation into disorder-mediated charge transport in InP nanowires in the statistical doping regime. At zero gate voltage, transport is well described by the space charge limited current model and hopping transport, but . . .

We have applied two ab initio based methods to study the dramatic change of magnetic properties across a series of strongly correlated electron systems consisting of cerium monopnictides and monochalcogenides. While, the fully ab initio method gives g . . .

For partially delocalized correlated f-electron systems, the key aspect of the electronic behavior is the hybridization of f electrons with the non-f-band electrons. This gives unusual properties including suppressed crystal-field splitting and highly . . .

Hybridization of moderately delocalized f electrons with band electrons gives rise to a highly anisotropic two-ion interaction, which, as Siemann and Cooper first showed, accounts well for the unusual magnetic behavior of CeDi. In the present paper it . . .

The structural, electronic, and magnetic properties of the 2Pt/5Fe/2Pt(111) system were investigated using the total energy full-potential linearized augmented-plane-wave method. The interplanar relaxation, determined by the atomic force approach, was . . .

Recently there has been a resurgence of intense experimental and theoretical interest on the Kondo physics of nanoscopic and mesoscopic systems due to the possibility of making experiments in extremely small samples. We have carried out exact diagonal . . .

We have studied the one-dimensional periodic, symmetric Anderson model at half filling in the presence of disorder using finite-temperature quantum Monte Carlo techniques. We have considered the disorder of both the hybridization between the local f-o . . .
