On-demand electrostatic coupling of individual precharacterized nano- and microparticles in a segmented Paul trap. | LitMetric
We present a novel versatile method for one-by-one coupling of single nano- and microparticles. The particles are levitated in a segmented linear Paul trap, which is ideal for fast particle characterization and assembly of two or more preselected particles by electrostatic attraction. The final compound particles remain in the trap or can be deposited on other structures. We present the assembly protocol with a theoretical background of particle stability. Results for different particle combinations showing electromagnetic coupling are presented as well as a method for the deposition on optical fibers.
