Controlled spin-torque driven domain wall motion using staggered magnetic nanowires

Autor: Mohammed, H., Risi, S. Al, Kosel, T. L. Jin3 J., Piramanayagam, S. N., Sbiaa, R.

The growing demand for storage, due to big data applications, cannot be met by hard disk drives. Domain wall (DW) memory devices such as racetrack memory offer an alternative route to achieve high capacity storage. In DW memory, control of domain wal

Polarization-Induced Zener Tunnel Junctions in Wide-Bandgap Heterostructures

Autor: Simon, J., Zhang, Z., Goodman, K., Kosel, T., Fay, P., Jena, D.

The large electronic polarization in III-V nitrides allow for novel physics not possible in other semiconductor families. In this work, interband Zener tunneling in wide-bandgap GaN heterojunctions is demonstrated by using polarization-induced electr

Intelligent location of simultaneously active acoustic emission sources: Part II

Autor: Kosel, T., Grabec, I.

Part I describes an intelligent acoustic emission locator, while Part II discusses blind source separation, time delay estimation and location of two continuous acoustic emission sources. Acoustic emission (AE) analysis is used for characterization a
