Anisotropic implantation damage build-up and crystal recovery in $β$ -Ga $_{2}$ O $_{3}$

Duarte Magalhães Esteves, Sérgio Magalhães, Ângelo Rafael Granadeiro da Costa +2

The present work aims at investigating the defect accumulation and recovery dynamics in the inherently anisotropic $β$ -Ga $_{2}$ O $_{3}$ lattice. A systematic Rutherford Backscattering S…

Effect of Annealing on Al Diffusion and its Impact on the Properties of Ga $_{2}$ O $_{3}$ Thin Films Deposited on c-plane Sapphire by RF Sputtering

Ana Sofia Sousa, Duarte M. Esteves, Tiago T. Robalo +4

Gallium oxide is a wide-bandgap semiconductor which has been steadily growing in popularity due to its ultra-wide bandgap, suitability for harsh environments and distinctive opto-e…

Microtubes and nanomembranes by ion-beam-induced exfoliation of $β$ -Ga $_{2}$ O $_{3}$

Duarte Magalhães Esteves, Ru He, Calliope Bazioti +8

This paper reports an innovative process to fabricate $β$ -Ga $_{2}$ O $_{3}$ microtubes and nanomembranes based on ion implantation in (100)-oriented single-crystals. We show that, un…

Coupling and induced depinning of magnetic domain walls in adjacent spin valve nanotracks

J. Sampaio, L. O'Brien, D. Petit +6

The magnetostatic interaction between magnetic domain walls (DWs) in adjacent nanotracks has been shown to produce strong inter-DW coupling and mutual pinning. In this paper, we ha…

Magnetic field sensor with voltage-tunable sensing properties

Witold Skowroński, Piotr Wiśniowski, Tomasz Stobiecki +3

We report on a magnetic field sensor based on CoFeB/MgO/CoFeB magnetic tunnel junctions. By taking advantage of the perpendicular magnetic anisotropy of the CoFeB/MgO interface, th…
