Laser-thinning of MoS2: on demand generation of a single-layer semiconductor
Andres Castellanos-Gomez, Maria Barkelid, Stijn M. Goossens +3
Single-layer MoS2 is an attractive semiconducting analogue of graphene that combines high mechanical flexibility with a large direct bandgap of 1.8 eV. On the other hand, bulk MoS2…
Carbon nanotubes: Nonlinear high-Q resonators with strong coupling to single-electron tunneling
Harold B. Meerwaldt, Gary A. Steele, Herre S. J. van der Zant
Carbon nanotubes (CNTs) are nonlinear high-Q resonators with strong coupling to single-electron tunneling. We begin by describing several methods to detect the flexural motion of a…
Mechanical properties of freely suspended semiconducting graphene-like layers based on MoS2
Andres Castellanos-Gomez, Menno Poot, Gary A. Steele +3
We fabricate freely suspended nanosheets of MoS2 which are characterized by quantitative optical microscopy and high resolution friction force microscopy. We study the elastic defo…
Strong and tunable mode coupling in carbon nanotube resonators
Andres Castellanos-Gomez, Harold B. Meerwaldt, Warner J. Venstra +2
The non-linear interaction between two mechanical resonances of the same freely suspended carbon nanotube resonator is studied. We find that in the Coulomb blockade regime, the non…
Elastic properties of freely suspended MoS2 nanosheets
Andres Castellanos-Gomez, Menno Poot, Gary A. Steele +3
We study the elastic deformation of few layers (5 to 25) thick freely suspended MoS2 nanosheets by means of a nanoscopic version of a bending test experiment, carried out with the…
