Opto-mechanical Manipulation of CrPbBr3 Perovskite Particles

Here, we have investigated the possibility of opto-mechanical manipulation of cubic halogenide perovskite particles CrPbBr
3
with a size in the range from 0.2–2.1μm. Numerical study revealed three regimes of trapping depending on the size of the particles: particle trapping in all 3 dimensions, particle trapping in plane orthogonal to propagation of the optical beam and no-trapping. We discuss the limitations of the method and propose a method for attaining particle trapping by engineering the wavefront of the optical beam.
