Ab initio calculation of ideal strength and phonon instability of graphene in tension
strength phonon instability graphene
2012/8/8
Graphene-based sp2-carbon nanostructures such as carbon nanotubes and nanofibers can fail
near their ideal strengths due to their exceedingly small dimensions. We have calculated the
phonon spectra ...
On the zero-field orbital magnetic susceptibility of Bloch electrons in graphene-like solids: Some rigorous results
Diamagnetism zero-field susceptibility two-dimensional electrons gas graphene semiconductors
2012/4/17
Starting with a nearest-neighbors tight-binding model, we rigorously investigate the bulk zero-field orbital susceptibility of a non-interacting Bloch electrons gas in graphene-like solids at fixed te...
We investigate two seemingly disjoint definitions of helicity, one commonly used in particle physics, the other one used when studying bilinear covariants of Clifford algebras. We can prove that the `...
Chiral tunneling in single and bilayer graphene
Chiral tunneling single-layer bilayer graphene its semiclassical theory
2011/7/28
Abstract: We review chiral (Klein) tunneling in single-layer and bilayer graphene and present its semiclassical theory, including the Berry phase and the Maslov index. Peculiarities of the chiral tunn...
Quantum Capacitance vs Chemical Potential Universal Curve and Interface Trap Parameter Extraction in Graphene Gated Structures
Quantum Capacitance hemical Potential Universal Curve Interface Trap Parameter Extraction Graphene Gated Structures
2010/11/25
We study influence of the interface traps unavoidably occurring at or near the interface
between the graphene sheets and the insulating substrate or top gate oxide on the
capacitance characteristics...
