Periodic spatial variation of the electron-phonon interaction in epitaxial graphene on Ru(0001
Andres Castellanos-Gomez, Gabino Rubio-Bollinger, Sara Barja +4
We have performed low temperature scanning tunnelling spectroscopy (STS) measurements on graphene epitaxially grown on Ru(0001). An inelastic feature, related to the excitation of…
Large and tunable photo-thermoelectric effect in single-layer MoS2
Michele Buscema, Maria Barkelid, Val Zwiller +3
We study the photoresponse of single-layer MoS2 field-effect transistors by scanning photocurrent microscopy. We find that, unlike in many other semiconductors, the photocurrent ge…
Electric field screening in atomically thin layers of MoS2: the role of interlayer coupling
Andres Castellanos-Gomez, Emmanuele Cappelluti, Rafael Roldán +3
The aim of this work is to study the electrostatic screening by single and few-layer MoS2 sheets by means of electrostatic force microscopy in combination with a non-linear Thomas-…
A simple strobe to study high-order harmonics and multifrequency oscillations in mechanical resonators
Andres Castellanos-Gomez
A simple strobe setup with potential to study higher-order eigenmodes and multifrequency oscillations in micromechanical resonators is described. It requires standard equipment, co…
Electronic inhomogeneities in graphene: the role of the substrate interaction and chemical doping
A. Castellanos-Gomez, Arramel, M. Wojtaszek +5
We probe the local inhomogeneities of the electronic properties of graphene at the nanoscale using scanning probe microscopy techniques. First, we focus on the study of the electro…
Highly reproducible low temperature scanning tunnelling microscopy and spectroscopy with in situ prepared tips
Andres Castellanos-Gomez, Gabino Rubio-Bollinger, Manuela Garnica +4
An in situ tip preparation procedure compatible with ultra-low temperature and high magnetic field scanning tunneling microscopes is presented. This procedure does not require addi…
