Ferroelectricity in epitaxially strained rhombohedral ZrO2 thin films
J. P. B. Silva, R. F. Negrea, M. C. Istrate +7
Zirconia and hafnia based thin films have attracted tremendous attention in the last decade due to their unexpected ferroelectric behavior at the nanoscale, which facilitates the d…
Magnetic superspace groups and symmetry constraints in incommensurate magnetic phases
J. M. Perez-Mato, J. L. Ribeiro, V. Petricek +1
Although superspace formalism has become the standard approach for the analysis of structurally modulated crystals, it has remained during the last thirty years almost unexplored a…
Adatoms in Graphene
Antonio H. Castro Neto, Valeri N. Kotov, Johan Nilsson +3
We review the problem of adatoms in graphene under two complementary points of view, scattering theory and strong correlations. We show that in both cases impurity atoms on the gra…
