Nucleation and Propagation of Traveling Charge Domains in a Planar AlGaN/GaN Triode Structure

physica status solidi (a), EarlyView.
This work presents a novel model for the nucleation of charge domain instabilities in semiconductors exhibiting negative differential drift velocity, identifying diffusion as the key factor inhibiting domain formation. A planar Gunn triode structure is proposed which overcomes obstacles to the realization of GaN‐based Gunn effect devices with ...

Structure and Migration Mechanisms of Oxygen Interstitial Defects in β‐Ga2O3

physica status solidi (b), EarlyView.
The structures and diffusion mechanisms of interstitial oxygen in different charge states in β‐Ga2O3 are extensively studied using density functional theory. The results provide a detailed map of the potential energy surface for oxygen interstitials in β‐Ga2O3 and demonstrate how these ions migrate between different rings in the structure.

Magnetic Hopfions as Local Rotations of the Uniform Magnetization Background

physica status solidi (RRL) – Rapid Research Letters, EarlyView.
The Hopf mapping of 3D coordinate space to the unit sphere m2 = 1 in the magnetization space m(r) can be parametrized by some angles. These angles are used to define a local rotation matrix to restore the hopfion magnetization configuration from the uniformly magnetized state for any Hopf indices.
