Oblique spin injection to graphene via geometry controlled magnetic nanowires

Autor: Toscano-Figueroa, Jesus C., Burrow, Daniel, Guarochico-Moreira, Victor H., Xie, Chengkun, Thomson, Thomas, Grigorieva, Irina V., Vera-Marun, Ivan J.

Publikováno v: npj Spintronics 2, 38 (2024)

We exploit the geometry of magnetic nanowires, which define 1D contacts to an encapsulated graphene channel, to introduce an out-of-plane component in the polarisation of spin carriers. By design, the magnetic nanowires traverse the angled sides of t

Thermopower in hBN/graphene/hBN superlattices

Autor: Guarochico-Moreira, Victor H., Anderson, Christopher R., Fal'ko, Vladimir, Grigorieva, Irina V., Tóvári, Endre, Hamer, Matthew, Gorbachev, Roman, Liu, Song, Edgar, James H., Principi, Alessandro, Kretinin, Andrey V., Vera-Marun, Ivan J.

Thermoelectric effects are highly sensitive to the asymmetry in the density of states around the Fermi energy and can be exploited as probes of the electronic structure. We experimentally study thermopower in high-quality monolayer graphene, within h

Exploring room temperature spin transport under band gap opening in bilayer graphene

Autor: Anderson, Christopher R., Natera-Cordero, Noel, Guarochico-Moreira, Victor H., Grigorieva, Irina V., Vera-Marun, Ivan J.

Publikováno v: Sci Rep 13, 10343 (2023)

We study the room-temperature electrical control of charge and spin transport in high-quality bilayer graphene, fully encapsulated with hBN and contacted via 1D spin injectors. We show that spin transport in this device architecture is measurable at

Tuneable spin injection in high-quality graphene with one-dimensional contacts

Autor: Guarochico-Moreira, Victor H., Sambricio, Jose L., Omari, Khalid, Anderson, Christopher R., Bandurin, Denis A., Toscano-Figueroa, Jesus C., Natera-Cordero, Noel, Watanabe, Kenji, Taniguchi, Takashi, Grigorieva, Irina V., Vera-Marun, Ivan J.

Publikováno v: Nano Lett. 2022, 22, 3, 935-941

Spintronics involves the development of low-dimensional electronic systems with potential use in quantum-based computation. In graphene, there has been significant progress in improving spin transport characteristics by encapsulation and reducing imp

Magnon-assisted tunnelling in van der Waals heterostructures based on CrBr3

Autor: Ghazaryan, Davit, Greenaway, Mark T., Wang, Zihao, Guarochico-Moreira, Victor H., Vera-Marun, Ivan J., Yin, Jun, Liao, Yuanxun, Morozov, Serge V., Kristanovski, Oleg, Lichtenstein, Alexander I., Katsnelson, Mikhail I., Withers, Fred, Mishchenko, Artem, Eaves, Laurence, Geim, Andre K., Novoselov, Kostya S., Misra, Abhishek

Publikováno v: Nature Electronics volume 1, pages 344-349 (2018)

The growing family of two-dimensional (2D) materials that are now available can be used to assemble van der Waals heterostructures with a wide range of properties. Of particular interest are tunnelling heterostructures, which have been used to study
