Report

Vertical engineering for large stimulated Brillouin scattering in unreleased silicon-based waveguides

Autor: Mercadé, Laura, Korovin, Alexander V., Pennec, Yan, Rouhani, Bahram Djafari, Martínez, Alejandro

Publikováno v: Phys. Rev. Applied 15, 034021 (2021)

Strong acousto-optic interaction in silicon-based waveguides generally requires releasing of the silicon core to avoid mechanical leakage into the underlying silica substrate. This complicates fabrication, limits thermalization, reduces the mechanica

Stabilization of $\varepsilon$-Fe$_2$O$_3$ epitaxial layer on MgO(111)/GaN via an intermediate $\gamma$-Fe$_2$O$_3$-phase

Autor: Ukleev, Victor, Volkov, Mikhail, Korovin, Alexander, Saerbeck, Thomas, Sokolov, Nikolai, Suturin, Sergey

Publikováno v: Phys. Rev. Materials 3, 094401 (2019)

In the present study we have demonstrated epitaxial stabilization of the metastable magnetically-hard $\varepsilon$-Fe$_2$O$_3$ phase on top of a thin MgO(111) buffer layer grown onto the GaN (0001) surface. The primary purpose to introduce a 4\,nm-t

Report

Tunable polymorphism of epitaxial iron oxides in the four-in-one ferroic-on-GaN system with magnetically ordered {\alpha}-, {\gamma}-, {\epsilon}-Fe2O3 and Fe3O4 layers

Autor: Suturin, Sergey, Korovin, Alexander, Gastev, Sergey, Volkov, Mikhail, Tabuchi, Masao, Sokolov, Nikolai

Publikováno v: Phys. Rev. Materials 2, 073403 (2018)

Hybridization of semiconducting and magnetic materials into a single heterostructure is believed to be potentially applicable to the design of novel functional spintronic devices. In the present work we report epitaxial stabilization of four magnetic
