Entanglement reduction induced by geometrical confinement in polymer thin films
Nicolás A. García, Jean-Louis Barrat
We report simulation results on melts of entangled linear polymers confined in a free-standing thin film. We study how the geometric constraints imposed by the confinement alter th…
Pattern formation mechanisms in sphere-forming diblock copolymer thin films
Leopoldo R. Gómez, Nicolás A. García, Richard A. Register +1
The order-disorder transition of a sphere-forming block copolymer thin film was numerically studied through a Cahn-Hilliard model. Simulations show that the fundamental mechanisms…
Length dependence of the resistance in graphite: Influence of ballistic transport
P. Esquinazi, J. Barzola-Quiquia, S. Dusari +1
Using a linear array of voltage electrodes with a separation of several micrometers on a nm thick and 30 m long multigraphene sample we show that the measured resistance do…
Evidence for semiconducting behavior with a narrow band gap of Bernal graphite
N. García, P. Esquinazi, J. Barzola-Quiquia +1
We have studied the resistivity of a large number of highly oriented graphite samples with areas ranging from several mm to a few m and thickness from nm to se…
Ballistic transport at room temperature in micrometer size multigraphene
S. Dusari, J. Barzola-Quiquia, P. Esquinazi +1
The intrinsic values of the carriers mobility and density of the graphene layers inside graphite, the well known structure built on these layers in the Bernal stacking configuratio…
Negative differential resistance in normal narrow bands - superconducting junctions with Andreev reflection
N. García, P. Esquinazi
We have calculated current-voltage characteristic curves for normal-superconducting junctions with Andreev reflections and different types of electronic bands. We found that when t…
