Show affiliationsWe report the fabrication and characterization of doubly clamped multi-walled carbon nanotubes (MWNTs). The devices were assembled by applying an electric field while the MWNTs were firmly clamped and suspended at both ends of a thick metal trench electrode in solution. The contacts were further processed using a focused ion beam. Final dimensions ranged from 100 to 150 nm in diameter and 1.5–4 µm in length. The fabricated devices were characterized by I–V curves, impedance measurements, and their mechanical deformation under a high pressure airflow. In the latter case, the resistance of a MWNT device varied linearly with the magnitude of the air pressure. These characteristics strongly suggest potential applications in fields such as nanoelectronics and sensors.
