Abstract The power conversion efficiency of solar cells is strongly impacted by an unwanted loss of charge carriers occurring at semiconductor surfaces and interfaces. Here the use of ion‐charged oxide nanolayers to enhance the passivation of silic

Dielectric-silicon interfaces are becoming ever more important to device performance. Charge inside a surface dielectric layer is neutralized in Si leading to an accumulation or inversion layer of free carriers. Additionally, states at the interface

We present a computational study of the compound Y Co 1 - x - y Fe x Cu y 5 for 0 ⩽ x , y ⩽ 0.2 . This compound was chosen as a prototype for investigating the cell boundary phase believed to play a key role in establishing the high coercivity of

A holistic approach for studying both the nature of atomic order and finite-temperature magnetostrictive behavior in the binary alloy Galfenol (${\mathrm{Fe}}_{1\ensuremath{-}x}{\mathrm{Ga}}_{x}, 0\ensuremath{\le}x\ensuremath{\le}0.25$) is presented.

The optimal amount of dysprosium in the highly magnetostrictive rare-earth compounds ${\mathrm{Tb}}_{1\ensuremath{-}x}{\mathrm{Dy}}_{x}{\mathrm{Fe}}_{2}$ for room-temperature applications has long been known to be $x=0.73$ (Terfenol-D). Here, we deri

${\mathrm{GdCo}}_{5}$ may be considered as two sublattices---one of Gd and one of Co---whose magnetizations are in antiparallel alignment, forming a ferrimagnet. Substitution of nickel in the cobalt sublattice of ${\mathrm{GdCo}}_{5}$ has been invest
