Few-layer antimonene electrical properties
Pablo Ares, Sahar Pakdel, Irene Palacio +10
Antimonene -- a single layer of antimony atoms -- and its few layer forms are among the latest additions to the 2D mono-elemental materials family. Numerous predictions and experim…
The effect of rippling on the mechanical properties of graphene
Guillermo Lopez-Polin, Cristina Gomez-Navarro, Julio Gomez-Herrero
Graphene is the stiffest material known so far but, due to its one-atom thickness, it is also very bendable. Consequently, free-standing graphene exhibit ripples that has major eff…
Mechanical Isolation of Highly Stable Antimonene under Ambient Conditions
Pablo Ares, Fernando Aguilar-Galindo, David Rodríguez-San-Miguel +6
Using mechanical exfoliation combined with a controlled double step transfer procedure we demonstrate that single layers of antimony can be readily produced. These flakes are not s…
Environmental Effects in Mechanical Properties of Few-layer Black Phosphorus
Miriam Moreno-Moreno, Guillermo Lopez-Polin, Andres Castellanos-Gomez +2
We report on the mechanical properties of few-layer black phosphorus (BP) nanosheets, in high vacuum and as a function of time of exposure to atmospheric conditions [1]. BP flakes…
An upper bound for the magnetic force gradient in graphite
David Martinez-Martin, Miriam Jaafar, Ruben Perez +2
Cervenka et al. have recently reported ferromagnetism along graphite steps. We present Magnetic Force microscopy (MFM) data showing that the signal along the steps is independent o…
Surface electric potential dynamic on graphite
D. Martinez-Martin, J. Gomez-Herrero
We observe variations on the surface potential of graphite samples that we attribute to the adsorption physisorption of tetracene isomers.
Tuning the conductance of single-walled carbon nanotubes by ion irradiation in the Anderson localization regime
C. Gomez-Navarro, P. J. De Pablo, J. Gomez-Herrero +4
Carbon nanotubes are a good realization of one-dimensional crystals where basic science and potential nanodevice applications merge. Defects are known to modify the electrical resi…
First principles study of the adsorption of C60 on Si(111)
Daniel Sanchez-Portal, Emilio Artacho, J. I. Pascual +3
The adsorption of C60 on Si(111) has been studied by means of first-principles density functional calculations. A 2x2 adatom surface reconstruction was used to simulate the terrace…
