Patterning Tri-Halide Perovskite Single Crystal Growth

Organic perovskites have been growing in the field of organic electronics, and lately field-effect transistors with single-crystalline perovskites have received more attention, because they should have ideal field-effect mobility and new crystal growth techniques have made them easier to synthesize. This research works to improve the reproducibility of the single-crystal growth as well as pattern the perovskite single crystals for better device reproducibility. We were successful in patterning the crystal growth, using silicon chips patterned via photolithography, and a custom-made clamp to even the pressure applied to the substrates. However, improved contact between the substrates and better control over the pressure applied during the annealing process is needed to improve the quality of the patterned crystal growth.
