Electrostatic trapping of single conducting nanoparticles between nanoelectrodes
For molecular electronics, one needs the ability to electrically address a single conducting molecule. We report on the fabrication of stable Pt electrodes with a spacing down to 4 nm and demonstrate a new deposition technique, i.e., electrostatic trapping, which can be used to bridge the electrodes in a controlled way with a single conducting nanoparticle such as a conjugated or metal–cluster ...
متن کاملElectrostatic Trapping of Ultracold Polar Molecules
This thesis describes the progress made in the production, spectroscopic characterization, and confinement of ultracold, polar NaCs molecules. A two-species magneto-optical trap (MOT) for the simultaneous cooling and trapping of sodium and cesium atoms is utilized for the creation of ultracold NaCs molecules via photoassociation. The molecules are detected via resonance-enhanced multi-photon io...
متن کاملOptical trapping of nanoparticles.
Optical trapping is a technique for immobilizing and manipulating small objects in a gentle way using light, and it has been widely applied in trapping and manipulating small biological particles. Ashkin and co-workers first demonstrated optical tweezers using a single focused beam. The single beam trap can be described accurately using the perturbative gradient force formulation in the case of...
متن کاملElectrostatic trapping of metastable NH molecules
We report on the Stark deceleration and electrostatic trapping of NH (a ∆) radicals. In the trap, the molecules are excited on the spin-forbidden A Π ← a ∆ transition and detected via their subsequent fluorescence to the X Σ ground state. The 1/e trapping time is 1.4 ± 0.1 s, from which a lower limit of 2.7 s for the radiative lifetime of the a ∆, v = 0, J = 2 state is deduced. The spectral pro...
