Impact of the angular alignment on the crystal field and intrinsic doping of bilayer graphene/BN heterostructures

Autor: Farrar, L. S., Maffione, G., Nguyen, V. -H., Watanabe, K., Taniguchi, T., Charlier, J. -Ch., Mailly, D., Ribeiro-Palau, R.

The energy gap of Bernal-stacked bilayer graphene can be tuned by applying a perpendicular electric field. The origin of this gap can be traced down to the breaking of its inversion symmetry by an onsite potential difference between the layers. This

Unconventional localization of electrons inside of a nematic electronic phase

Autor: Farrar, L., Zajicek, Z., Morfoot, A. B., Bristow, M., Humphries, O. S., Haghighirad, A. A., McCollam, A., Bending, S. J., Coldea, A. I.

Publikováno v: PNAS Vol.119 No.43 e220040511 (2022)

The magnetotransport behaviour inside the nematic phase of bulk FeSe reveals unusual multiband effects that cannot be reconciled with a simple two-band approximation proposed by surface-sensitive spectroscopic probes. In order to understand the role

Non-identical moir\'e twins in bilayer graphene

Autor: Arrighi, E., Nguyen, V. -H., Di Luca, M., Maffione, G., Hong, Y., Farrar, L., Watanabe, K., Taniguchi, T., Mailly, D., Charlier, J. -C., Ribeiro-Palau, R.

The superlattice obtained by aligning a monolayer graphene and boron nitride (BN) inherits from the hexagonal lattice a sixty degrees periodicity with the layer alignment. It implies that, in principle, the properties of the heterostructure must be i

Observing the suppression of superconductivity in RbEuFe$_4$As$_4$ by correlated magnetic fluctuations

Autor: Collomb, D., Bending, S. J., Koshelev, A. E., Smylie, M. P., Farrar, L., Bao, J. -K., Chung, D. Y., Kanatzidis, M. G., Kwok, W. -K., Welp, U.

Publikováno v: Phys. Rev. Lett. 126, 157001 (2021)

In this letter, we describe quantitative magnetic imaging of superconducting vortices in RbEuFe$_4$As$_4$ in order to investigate the unique interplay between the magnetic and superconducting sublattices. Our scanning Hall microscopy data reveal a pr

Coherent phonons and the interplay between charge density wave and Mott phases in 1$T$-TaSe$_{2}$

Autor: Sayers, C. J., Hedayat, H., Ceraso, A., Museur, F., Cattelan, M., Hart, L. S., Farrar, L. S., Conte, S. Dal, Cerullo, G., Dallera, C., Da Como, E., Carpene, E.

Publikováno v: Phys. Rev. B 102, 161105(R) (2020)

1$T$-TaSe$_{2}$ is host to coexisting strongly-correlated phases including charge density waves (CDWs) and an unusual Mott transition at low temperature. Here, we investigate coherent phonon oscillations in 1$T$-TaSe$_{2}$ using a combination of time

Correlation between crystal purity and the charge density wave in 1$T$-VSe$_2$

Autor: Sayers, C. J., Farrar, L. S., Bending, S. J., Cattelan, M., Jones, A. J. H., Fox, N. A., Kociok-Köhn, G., Koshmak, K., Laverock, J., Pasquali, L., Da Como, E.

Publikováno v: Phys. Rev. Materials 4, 025002 (2020)

We examine the charge density wave (CDW) properties of 1$T$-VSe$_{2}$ crystals grown by chemical vapour transport (CVT) under varying conditions. Specifically, we find that by lowering the growth temperature ($T_{\mathrm{g}}$ $<$ 630$^{\circ}$C), the
