(LaCrO) /SrCrO superlattices as transparent p-type semiconductors with finite magnetization.

The electronic and magnetic properties of (LaCrO) /SrCrO superlattices are investigated using first principles calculations. We show that the magnetic moments in the two CrO layers sandwiching the SrO layer compensate each other for even but give rise to a finite magnetization for odd , which is explained by charge ordering with Cr and Cr ions arranged in a checkerboard pattern. The Cr ions induce in-gap hole states at the interface, implying that the transparent superlattices are p-type semiconductors.

Spin-charge conversion in NiMnSb Heusler alloy films.

Half-metallic Heusler alloys are attracting considerable attention because of their unique half-metallic band structures, which exhibit high spin polarization and yield huge magnetoresistance ratios. Besides serving as ferromagnetic electrodes, Heusler alloys also have the potential to host spin-charge conversion. Here, we report on the spin-charge conversion effect in the prototypical Heusler alloy NiMnSb.

Implementation of transmission functions for an optimized three-terminal quantum dot heat engine.

We consider two modifications of a recently proposed three-terminal quantum dot heat engine. First, we investigate the necessity of the thermalization assumption, namely that electrons are always thermalized by inelastic processes when traveling across the cavity where the heat is supplied. Second, we analyze various arrangements of tunneling-coupled quantum dots in order to implement a transmission function that is superior to the Lorentzian transmission function of a single quantum dot.

Unravelling the interplay of geometrical, magnetic and electronic properties of metal-doped graphene nanomeshes.

Graphene nanomeshes (GNMs), formed by creating a superlattice of pores in graphene, possess rich physical and chemical properties. Many of these properties are determined by the pore geometry. In this work, we use first principles calculations to study the magnetic and electronic properties of metal-doped nitrogen-passivated GNMs.

Defect engineering of the electronic transport through cuprous oxide interlayers.

The electronic transport through Au-(Cu2O)n-Au junctions is investigated using first-principles calculations and the nonequilibrium Green's function method. The effect of varying the thickness (i.e.
