Strong spin-phonon coupling between a single-molecule magnet and a carbon nanotube nanoelectromechanical system.
Magnetic relaxation processes were first discussed for a crystal of paramagnetic transition ions. It was suggested that mechanical vibrations of the crystal lattice (phonons) modulate the crystal electric field of the magnetic ion, thus inducing a 'direct' relaxation between two different spin states. Direct relaxation has also been predicted for single-molecule magnets with a large spin and a ...
متن کاملMechanical detection of carbon nanotube resonator vibrations.
Bending-mode vibrations of carbon nanotube resonators were mechanically detected in air at atmospheric pressure by means of a novel scanning force microscopy method. The fundamental and higher order bending eigenmodes were imaged at up to 3.1 GHz with subnanometer resolution in vibration amplitude. The resonance frequency and the eigenmode shape of multiwall nanotubes are consistent with the el...
متن کاملPhonon runaway in carbon nanotube quantum dots
Phonon runaway in carbon nanotube quantum dots" (2008). Other Nanotechnology Publications. Paper 93. We explore electronic transport in a nanotube quantum dot strongly coupled with vibrations and weakly with leads and the thermal environment. We show that the recent observation of anomalous conductance signatures in single-walled carbon nanotube quantum dots ͓B. can be understood quantitatively ...
متن کاملSwitchable Coupling of Vibrations to Two-Electron Carbon-Nanotube Quantum Dot States.
We report transport measurements on a quantum dot in a partly suspended carbon nanotube. Electrostatic tuning allows us to modify and even switch "on" and "off" the coupling to the quantized stretching vibration across several charge states. The magnetic-field dependence indicates that only the two-electron spin-triplet excited state couples to the mechanical motion, indicating mechanical coupl...
متن کاملOn the Effect of Electron-Phonon Interaction Parameters on the Performance of Carbon Nanotube Based Transistors
Exceptional electronic and mechanical properties together with nanoscale diameter make carbon nanotubes (CNTs) promising candidates for nanoscale transistors. Semiconducting CNTs can be used as a channel for field-effect transistors (FETs), and metallic CNTs can serve as interconnect wires. In short devices carrier transport through the device is nearly ballistic [1]. The non-equilibrium Green’...
