Charged Hybrid Microstructures in Transparent Thin-Film ITO Traps: Localization and Optical Control

Abstract

In the present study, we propose a new transparent thin-film ITO surface radio-frequency (RF) trap. Charged hybrid microstructures were localized in the developed ITO trap. We show, analytically and experimentally, that the position of the localization zones in the trapped hybrid structure are stable. The transfer of charged particles between localization zones was studied under the action of gravity-compensating laser radiation. We highlight the advantages of transparent thin-film ITO traps to investigate and manipulate charged particles.

Fractal Quasi-Coulomb Crystals in Ion Trap with Cantor Dust Electrode Configuration

“…Localization of the charged particles in SEDTs is based on their interaction with the AC electric field around the flat conducting electrodes. The spatial position of the particles in the SEDT is strictly dependent on the shape and the arrangement of the electrodes on the dielectric substrate.The specific electrode geometry results in multiple isolated regions of localization (potential wells) in a single trap [10,11]. Quasi-Coulomb crystals can be formed during the many-body localization in a multi-well trap.…”

“…The best-studied linear quadrupole Paul traps provide a single potential well [8]. Otherwise, in the case of surface traps consisting of thin film electrodes deposited on a substrate, there can be either single-well or multi-well potential distribution [9][10][11]. The potential distribution appears to be defined by electrode geometry and by electrical supply parameters.…”

“…The potential distribution appears to be defined by electrode geometry and by electrical supply parameters. Moreover, such a system is sensitive to external effects [11]. Thus, the controllable potential distribution can be easily implemented with surface traps [12,13].…”
