Visualization and Manipulation of Bilayer Graphene Quantum Dots with Broken Rotational Symmetry and Nontrivial Topology
Zhehao Ge, Frederic Joucken, Eberth Quezada +8
Electrostatically defined quantum dots (QDs) in Bernal stacked bilayer graphene (BLG) are a promising quantum information platform because of their long spin decoherence times, hig…
Electronic and transport properties of anisotropic semiconductor quantum wires
S. M. Cunha, D. R. da Costa, L. C. Felix +2
Within the effective-mass approximation, we theoretically investigated the electronic and transport properties of 2D semiconductor quantum wires (QWs) with anisotropic effective ma…
Two dimensional electron gas in a non-Euclidean space
R. N. Costa Filho, S. F. S. Oliveira, V. Aguiar
A charged particle in the presence of a magnetic field is studied in the position dependent operator formalism. Instead of a quantum harmonic oscillator, the solution of the result…
Current modulation in graphene p-n junctions with external fields
F. R. V. Araújo, D. R. da Costa, A. C. S. Nascimento +1
In this work we describe a proposal for a graphene-based nanostructure that modulates electric current even in the absence of a gap in the band structure. The device consists of a…
Electronic properties of bilayer graphene catenoid bridge
J. E. G. Silva, J. Saraiva, T. M. Santhiago +2
We study the properties of an electron on a catenoid surface. The catenoid is understood as a realization of a bridge connecting two graphene layer by a smooth surface. The curvatu…
