Half-metallic Zinc-Blende Compounds

We report first-principles calculations of zinc-blende half-metals, identifying systems for epitaxial growth with semiconductors, and present calculations for CrAs/GaAs multilayers. We find that half-metallicity is conserved troughout the heterostructure, making this a good candidate for spintronics applications.

Magnetization noise in magnetoelectronic nanostructures.

By scattering theory we show that spin current noise in normal electric conductors in contact with nanoscale ferromagnets increases the magnetization noise by means of a fluctuating spin-transfer torque. Johnson-Nyquist noise in the spin current is related to the increased Gilbert damping due to spin pumping, in accordance with the fluctuation-dissipation theorem. Spin current shot noise in the...

Phase mapping of aging process in InN nanostructures: oxygen incorporation and the role of the zinc blende phase.

Uncapped InN nanostructures undergo a deleterious natural aging process at ambient conditions by oxygen incorporation. The phases involved in this process and their localization is mapped by transmission electron microscopy (TEM)-related techniques. The parent wurtzite InN (InN-w) phase disappears from the surface and gradually forms a highly textured cubic layer that completely wraps up a InN-...

Ultrafast magnetization dynamics of spintronic nanostructures.

The ultrafast (sub-nanosecond) magnetization dynamics of ferromagnetic thin films and elements that find application in spintronic devices is reviewed. The major advances in the understanding of magnetization dynamics in the two decades since the discovery of giant magnetoresistance and the prediction of spin-transfer torque are discussed, along with the plethora of new experimental techniques ...

Importance of second-order piezoelectric effects in zinc-blende semiconductors.

We show that the piezoelectric effect that describes the emergence of an electric field in response to a crystal deformation in III-V semiconductors such as GaAs and InAs has strong contributions from second-order effects that have been neglected so far. We calculate the second-order piezoelectric tensors using density-functional theory and obtain the piezoelectric field for [111]-oriented In(x...
