Hybrid Field-Effect Transistors and Photodetectors Based on Organic Semiconductor and CsPbI₃ Perovskite Nanorods Bilayer Structure.

ABSTRACT: The outstanding performances of nanostructured all-inorganic CsPbX₃ (X = I, Br, Cl) perovskites in optoelectronic applications can be attributed to their unique combination of a suitable bandgap, high absorption coefficient, and long carrier lifetime, which are desirable for photodetectors. However, the photosensing performances of the CsPbI₃ nanomaterials are limited by their low charge-transport efficiency. In this study, a phototransistor with a bilayer structure of an organic semiconductor layer of 2,7-dioctyl [1] benzothieno[3,2-b] [1] benzothiophene and CsPbI₃ nanorod layer was fabricated. The high-quality CsPbI₃ nanorod layer obtained using a simple dip-coating method provided decent transistor performance of the hybrid transistor device.
