Quantum Dots at Room Temperature carved out from Few-Layer Graphene
Amelia Barreiro, Herre S. J. van der Zant, Lieven M. K. Vandersypen
We present graphene quantum dots endowed with addition energies as large as 1.6 eV, fabricated by the controlled rupture of a graphene sheet subjected to a large electron current i…
Lattice Expansion in Seamless Bi layer Graphene Constrictions at High Bias
Felix Boerrnert, Amelia Barreiro, Daniel Wolf +4
Our understanding of sp2 carbon nanostructures is still emerging and is important for the development of high performance all carbon devices. For example, in terms of the structura…
Graphene at high bias: cracking, layer by layer sublimation and fusing
Amelia Barreiro, Felix Boerrnert, Mark H. Ruemmeli +2
Graphene and few-layer graphene at high bias expose a wealth of phenomena due to the high temperatures reached. With in-situ transmission electron microscopy (TEM) we observe direc…
Mechanical cleaning of graphene
A. M. Goossens, V. E. Calado, A. Barreiro +3
Contamination of graphene due to residues from nanofabrication often introduces background doping and reduces charge carrier mobility. For samples of high electronic quality, post-…
Room-temperature gating of molecular junctions using few-layer graphene nanogap electrodes
Ferry Prins, Amelia Barreiro, Justus W. Ruitenberg +4
We report on a method to fabricate and measure gateable molecular junctions which are stable at room temperature. The devices are made by depositing molecules inside a few-layer gr…
Current-voltage characteristics of graphene devices: interplay between Zener-Klein tunneling and defects
Niels Vandecasteele, Amelia Barreiro, Michele Lazzeri +2
We report a theoretical/experimental study of current-voltage characteristics (I-V) of graphene devices near the Dirac point. The I-V can be described by a power law (I \propto V^α…
