Biased Bilayer Graphene: Semiconductor with a Gap Tunable by the Electric Field Effect
Eduardo V. Castro,Kostya S. Novoselov,Sergey V. Morozov,Nuno M. R. Peres,J. M. B. Lopes dos Santos,Johan Nilsson,Francisco Guinea,Andre K. Geim,A. H. Castro Neto,A. H. Castro Neto +9 more
TL;DR: It is demonstrated that the electronic gap of a graphene bilayer can be controlled externally by applying a gate bias and can be changed from zero to midinfrared energies by using fields of less, approximately < 1 V/nm, below the electric breakdown of SiO2.

Eduardo V. Castro,J. M. B. Lopes dos Santos,Nuno M. R. Peres,K. S. Novoselov,S. V. Morozov,A. K. Geim,Francisco Guinea,Johan Nilsson,A. H. Castro Neto +8 more
TL;DR: In this paper, the electronic gap of a graphene bilayer can be controlled externally by applying a gate bias, and the gap can be changed from zero to mid-infrared energies by using fields of less, approximately < 1 V/nm, below the electric breakdown of SiO2.
Journal ArticleDOI
Electrically detected interferometry of Majorana fermions in a topological insulator.
TL;DR: This work shows how a pair of neutral Majorana fermions can be converted reversibly into a charged Dirac fermion, and enables electrical detection of a qubit by an interferometric measurement.
Journal ArticleDOI
Splitting of a Cooper Pair by a Pair of Majorana Bound States
TL;DR: In this article, the nonlocal scattering process dominates over local Andreev reflection involving a single bound state, and the low-temperature and low-frequency fluctuations of currents into the two bound states are maximally correlated.
Journal ArticleDOI
Probing the electronic structure of bilayer graphene by Raman scattering
Leandro M. Malard,Johan Nilsson,D. C. Elias,J. C. Brant,Flavio Plentz,E. S. Alves,A. H. Castro Neto,Marcos A. Pimenta +7 more
TL;DR: In this paper, the electronic structure of bilayer graphene was investigated from a resonant Raman study of the band using different laser excitation energies, revealing the difference of the effective masses of electrons and holes.
