Nanoelectromechanical systems (NEMS) coupled to a single-molecule magnet: Application to study the angular momentum conservation and nano-magnetometry
Final Report Abstract
Carbon nanotubes (CNTs) have become essential building blocks for nano-electromechanical systems (NEMS). Their low mass and high Young's modulus give rise to high oscillation frequencies, therefore enabling ground-state cooling with state-of-the-art cryogenics and a large zero-point motion in the quantum regime. Moreover, the strong coupling between nanomechanical motion and single-electron tunnelling in high-Q CNT NEMS allows electronic excitation and detection of the nanomechanical motion. As such, CNT-NEMS can be used for ultrasensitive mass sensing or as magnetic torque detectors for single spin systems. The aim of this project was and is to develop prototypes of hybrid molecular devices with nanomechanical systems, which open up new avenues for faster readout of molecular spin states, for the investigation of angular momentum conservation and non-classical motion states. In the long term, applications in quantum electronics are also expected.
