Moving magnetic domain walls with sound alone
Alejandro Rivelles, RocÃo Yanes, Luis Torres +18
Surface Acoustic Waves (SAW) have been used in spintronic applications to decrease the magnetic field or the electric current required to act on the magnetization. A common belief…
Structural and optical properties of self-assembled AlN nanowires grown on SiO2/Si substrates by molecular beam epitaxy
Ž. GaÄeviÄ, J. Grandal, Q. Guo +4
Self assembled AlN nanowires (NWs) are grown by plasma assisted molecular beam epitaxy (PAMBE) on SiO2 / Si (111) substrates. Using a combination of in-situ reflective high energy…
Self-regulated radius of spontaneously formed GaN nanowires in molecular beam epitaxy
Sergio Fernández-Garrido, Vladimir M. Kaganer, Karl K. Sabelfeld +5
We investigate the axial and radial growth of GaN nanowires upon a variation of the Ga flux during molecular beam epitaxial growth. An increase in the Ga flux promotes radial growt…
A growth diagram for plasma-assisted molecular beam epitaxy of GaN nanocolumns on Si(111)
S. Fernández-Garrido, J. Grandal, E. Calleja +2
The morphology of GaN samples grown by plasma-assisted molecular beam epitaxy on Si(111) was systematically studied as a function of impinging Ga/N flux ratio and growth temperatur…
