Giant ultra-broadband photoconductivity in twisted graphene heterostructures
Hitesh Agarwal, Krystian Nowakowski, Andres Forrer +12
The requirements for broadband photodetection are becoming exceedingly demanding in hyperspectral imaging. Whilst intrinsic photoconductor arrays based on mercury cadmium telluride…
Engineering high quality graphene superlattices via ion milled ultra-thin etching masks
David Barcons Ruiz, Hanan Herzig Sheinfux, Rebecca Hoffmann +8
Nanofabrication research pursues the miniaturization of patterned feature size. In the current state of the art, micron scale areas can be patterned with features down to ~ 30 nm p…
Strong coupling between mechanical modes in a nanotube resonator
A. Eichler, M. del Álamo Ruiz, J. A. Plaza +1
We report on the nonlinear coupling between the mechanical modes of a nanotube resonator. The coupling is revealed in a pump-probe experiment where a mode driven by a pump force is…
Dissipative and conservative nonlinearity in carbon nanotube and graphene mechanical resonators
J. Moser, A. Eichler, B. Lassagne +5
Graphene and carbon nanotubes represent the ultimate size limit of one and two-dimensional nanoelectromechanical resonators. Because of their reduced dimensionality, graphene and c…
Mechanical detection of carbon nanotube resonator vibrations
D. Garcia-Sanchez, A. San Paulo, M. J. Esplandiu +4
Bending-mode vibrations of carbon nanotube resonator devices were mechanically detected in air at atmospheric pressure by means of a novel scanning force microscopy method. The fun…
Suppression of tunneling into multi-wall carbon nanotubes
A. Bachtold, M. de Jonge, K. Grove-Rasmussen +3
We have studied tunneling of electrons into multi-wall carbon nanotubes. Nanotube/electrode interfaces with low transparency as well as nanotube/nanotube junctions created with ato…
