Atomic resolution mapping of localized phonon modes at grain boundaries
Benedikt Haas, Tara M. Boland, Christian Elsässer +5
Phonon scattering at grain boundaries (GBs) is significant in controlling nanoscale device thermal conductivity. However, GBs could also act as waveguides for selected modes. To me…
Effective screening of medium-assisted Van der Waals interactions between embedded particles
Johannes Fiedler, Michael Walter, Stefan Yoshi Buhmann
The effect of an implicit medium on dispersive interactions of particle pairs is discussed and simple expressions for the correction relative to vacuum are derived. We show that a…
Confined Electron and Hole States in Semiconducting Carbon Nanotube sub-10 nm Artificial Quantum Dots
Gilles Buchs, Dario Bercioux, Leonhard Mayrhofer +1
We show that quantum confinement in the valence and conduction bands of semiconducting single-walled carbon nanotubes can be engineered by means of artificial defects. This ability…
Superlubric to stick-slip sliding of incommensurate graphene flakes on graphite
M. M. van Wijk, M. Dienwiebel, J. W. M. Frenken +1
We calculate the friction of fully mobile graphene flakes sliding on graphite. For incommensurately stacked flakes, we find a sudden and reversible increase in friction with load,…
Rashba spin-orbit interaction in graphene armchair nanoribbons
Lucia Lenz, Daniel F. Urban, Dario Bercioux
We study graphene nanoribbons (GNRs) with armchair edges in the presence of Rashba spin-orbit interaction (RSOI). We impose the boundary conditions on the tight binding Hamiltonian…
Adiabatic pumping in the quasi-one-dimensional triangle lattice
M. Schulze, D. Bercioux, D. F. Urban
We analyze the properties of the quasi-one-dimensional triangle lattice emphasizing the occurrence of flat bands and band touching via the tuning of the lattice hopping parameters…
Transfer-free Grown Bilayer Graphene Transistors for Digital Applications
Pia Juliane Wessely, Frank Wessely, Emrah Birinci +2
We invented a novel method to fabricate graphene transistors on oxidized silicon wafers without the need to transfer graphene layers. By means of catalytic chemical vapor depositio…
Transfer-free fabrication of graphene transistors
Pia Juliane Wessely, Frank Wessely, Emrah Birinci +2
We invented a method to fabricate graphene transistors on oxidized silicon wafers without the need to transfer graphene layers. To stimulate the growth of graphene layers on oxidiz…
Silicon-CMOS Compatible In-Situ CCVD Grown Graphene Transistors with Ultra-High On/Off-Current Ratio
Pia Juliane Wessely, Frank Wessely, Emrah Birinci +3
By means of catalytic chemical vapor deposition (CCVD) in-situ grown monolayer graphene field-effect transistors (MoLGFETs) and bilayer graphene transistors (BiLGFETs) are realized…
Pseudo-spin-dependent scattering in carbon nanotubes
Leonhard Mayrhofer, Dario Bercioux
The breaking of symmetry is the ground on which many physical phenomena are explained. This is important in particular for bipartite lattice structure as graphene and carbon nanotu…
Spin-dependent transport through interacting graphene armchair nanoribbons
Sonja Koller, Leonhard Mayrhofer, Milena Grifoni
We investigate spin effects in transport across fully interacting, finite size graphene armchair nanoribbons (ACNs) contacted to collinearly spin-polarized leads. In such systems,…
Graphene armchair nanoribbon single-electron transistors: The peculiar influence of end states
Sonja Koller, Leonhard Mayrhofer, Milena Grifoni
We present a microscopic theory for interacting graphene armchair nanoribbon quantum dots. Long range interaction processes are responsible for Coulomb blockade and spin-charge sep…
Vibrational modes and low-temperature thermal properties of graphene and carbon nanotubes: A minimal force-constant model
J. Zimmermann, P. Pavone, G. Cuniberti
We present a phenomenological force-constant model developed for the description of lattice dynamics of sp2 hybridized carbon networks. Within this model approach, we introduce a n…
