Lattice-matched epitaxial graphene grown on boron nitride (2017)
Journal Article
Davies, A., Albar, J., Summerfield, A., Thomas, J. C., Cheng, T. S., Korolkov, V. V., …Beton, P. H. (2018). Lattice-matched epitaxial graphene grown on boron nitride. Nano Letters, 18(1), https://doi.org/10.1021/acs.nanolett.7b04453

Lattice-matched graphene on hexagonal boron nitride is expected to lead to the formation of a band-gap but requires the formation of highly strained material and has not hitherto been realised. We demonstrate that aligned, lattice-matched graphene ca... Read More about Lattice-matched epitaxial graphene grown on boron nitride.

Magnetic field tunable vortex diode made of YBa2Cu3O7−δ Josephson junction asymmetrical arrays (2017)
Journal Article
Chesca, B., John, D., Pollett, R., Gaifullin, M., Cox, J., Mellor, C., & Savelev, S. (in press). Magnetic field tunable vortex diode made of YBa2Cu3O7−δ Josephson junction asymmetrical arrays. Applied Physics Letters, 111(6), doi:10.1063/1.4997741

Several Josephson ratchets designed as asymmetrically structured parallel-series arrays of Josephson junctions made of YBa2Cu3O7−δ have been fabricated. From the current-voltage characteristics measured for various values of applied magnetic field, B...

Microwave Generation in Synchronized Semiconductor Superlattices (2017)
Journal Article
Gaifullin, M., Alexeeva, N., Hramov, A., Makarov, V., Maksimenko, V., Koronovskii, A., …Balanov, A. (2017). Microwave Generation in Synchronized Semiconductor Superlattices. Physical Review Applied, 7(4), https://doi.org/10.1103/PhysRevApplied.7.044024

We study high-frequency generation in a system of electromagnetically coupled semiconductor superlattices fabricated on the same doped substrate. Applying a bias voltage to a single superlattice generates high-frequency current oscillations. We demon... Read More about Microwave Generation in Synchronized Semiconductor Superlattices.
