Tuning the polarized quantum phonon transmission in graphene nanoribbons
P. Scuracchio, A. Dobry, F. Peeters +1
We propose systems that allow a tuning of the phonon transmission function T() in graphene nanoribbons by using C isotope barriers, antidot structures, and distinct bound…
The role of atomic vacancies and boundary conditions on ballistic thermal transport in graphene nanoribbons
P. Scuracchio, S. Costamagna, F. M. Peeters +1
Quantum thermal transport in armchair and zig-zag graphene nanoribbons are investigated in the presence of single atomic vacancies and subject to different boundary conditions. We…
Thermomechanical properties of a single hexagonal boron nitride sheet
Sandeep Kumar Singh, M. Neek-Amal, S. Costamagna +1
Using atomistic simulations we investigate the thermodynamical properties of a single atomic layer of hexagonal boron nitride (h-BN). The thermal induced ripples, heat capacity, an…
Thermal properties of fluorinated graphene
S. K. Singh, S. Goverapet Srinivasan, M. Neek-Amal +3
Large scale atomistic simulations using the reactive force field approach (ReaxFF) are implemented to investigate the thermomechanical properties of fluorinated graphene (FG). A ne…
Partially unzipped carbon nanotubes as magnetic field sensors
S. Costamagna, A. Schulz, L. Covaci +1
The conductance, , through graphene nanoribbons (GNR) connected to a partially unzipped carbon nanotube (CNT) is studied in the presence of an external magnetic field applied…
From the 2D graphene honeycomb lattice to 1D nanoribbons: dimensional crossover signals in the structural thermal fluctuations
S. Costamagna, A. Dobry
We study the dimensional crossover from 2D to 1D type behavior, which takes place in the thermal excited rippling of a graphene honeycomb lattice, when one of the dimensions of the…
Spectral gap induced by structural corrugation in armchair graphene nanoribbons
S. Costamagna, O. Hernandez, A. Dobry
We study the effects of the structural corrugation or rippling on the electronic properties of undoped armchair graphene nanoribbons (AGNR). First, reanalyzing the single corrugate…
