Tailoring the thermal expansion of graphene via controlled defect creation
Guillermo López-Polín, Maria Ortega, J. G. Vilhena +5
Contrary to most materials, graphene exhibits a negative thermal expansion coefficient (TEC), i.e it contracts when heated. This contraction is due to the thermal excitation of low…
Identification and characterization of icosahedral metallic nanowires
Samuel Peláez, Carlo Guerrero, Ricardo Paredes +2
We present and discuss an algorithm to identify and characterize the long icosahedral structures (staggered pentagonal nanowires with 1-5-1-5 atomic structure) that appear in Molec…
Statistical analysis of Ni nanowires breaking processes: a numerical simulation study
P. García-Mochales, R. Paredes, S. Peláez +1
A statistical analysis of the breaking behavior of Ni nanowires is presented. Using molecular dynamic simulations, we have determined the time evolution of both the nanowire atomic…
Ballistic resistivity in aluminum nanocontacts
A. Hasmy, A. J. Perez-Jimenez, J. J. Palacios +5
One of the major industrial challenges is to profit from some fascinating physical features present at the nanoscale. The production of dissipationless nanoswitches (or nanocontact…
From favorable atomic configurations to supershell structures: a new interpretation of conductance histograms
A. Hasmy, E. Medina, P. A. Serena
Title: From favorable atomic configurations to supershell structures: a new interpretation of conductance histograms Authors: A. Hasmy (IVIC), E. Medina (IVIC), P.A. Serena (CSIC,I…
Free-electron Model for Mesoscopic Force Fluctuations in Nanowires
S. Blom, H. Olin, J. L. Costa-Kramer +4
When two metal electrodes are separated, a nanometer sized wire (nanowire) is formed just before the contact breaks. The electrical conduction measured during this retraction proce…
