Multiferroic Two-Dimensional Materials
L. Seixas, A. S. Rodin, A. Carvalho +1
The relation between unusual Mexican-hat band dispersion, ferromagnetism and ferroelasticity is investigated using a combination of analytical, first-principles and phenomenologica…
Atomically thin dilute magnetism in Co-doped phosphorene
L. Seixas, A. Carvalho, A. H. Castro Neto
Two-dimensional dilute magnetic semiconductors can provide fundamental insights in the very nature of magnetic orders and their manipulation through electron and hole doping. Despi…
Exciton binding energies and luminescence of phosphorene under pressure
L. Seixas, A. S. Rodin, A. Carvalho +1
The optical response of phosphorene can be gradually changed by application of moderate uniaxial compression, as the material undergoes the transition into an indirect gap semicond…
Tunable optical properties of multilayers black phosphorus thin films
Tony Low, A. S. Rodin, A. Carvalho +4
Black phosphorus thin films might offer attractive alternatives to narrow gap compound semiconductors for optoelectronics across mid- to near-infrared frequencies. In this work, we…
Gate-tuning of graphene plasmons revealed by infrared nano-imaging
Z. Fei, A. S. Rodin, G. O. Andreev +12
Surface plasmons are collective oscillations of electrons in metals or semiconductors enabling confinement and control of electromagnetic energy at subwavelength scales. Rapid prog…
Selected Topics in Graphene physics
Antonio H. Castro Neto
Graphene research is currently one of the largest fields in condensed matter. Due to its unusual electronic spectrum with Dirac-like quasiparticles, and the fact that it is a uniqu…
