Carbon nanotube transfer into complex devices with commercial quartz tuning forks — •Patrick Steger, Niklas Hüttner, Richard Graaf, Alexander Albang, Stefan Blien, and Andreas K. Hüttel — Institute for Experimental and Applied Physics, University of Regensburg, 93040, Regensburg, Germany

Our work focuses on coupling suspended, clean carbon nanotubes (CNTs) to a superconducting coplanar waveguide (CPW) resonator for experiments in the field of optomechanics. However, device fabrication is challenging. To increase our fabrication yield we separate the CVD process for CNT growth from the rest of the device fabrication. CNTs are then transferred to the device in a second step. Our transfer setup allows in situ precharacterization of the CNT during the transfer process. When a suitable CNT is found, the transfer process is finished by cutting the tube with current pulses at both ends.

Using commercial quartz tuning forks as CNT growth substrate produces high quality samples with a good yield and relatively low fabrication effort. Fabrication of customized fork structures might help to further enhance the yield.
