Abstract

Benefiting from their extraordinary physical properties, methylammonium lead halide perovskites (PVKs) have attracted significant attention in optoelectronics. However, the PVK-based devices suffer from low carrier mobility and high operation voltage. Here, we utilize sorted semiconducting single-walled carbon nanotubes (95% s-SWCNTs) to enhance the performance of thin-film transistors (TFTs) based on the mixed-cation perovskite (MA1-xFAx)Pb(I1-xBrx)3, enabling mixed-dimensional solution-processed electronics with high mobility (32.25 cm2/(V s)) and low voltage (∼3 V) operation. The resulting mixed-dimensional PVK/SWCNT TFTs possess ON/OFF ratios on the order of 107, enabling the fabrication of high-gain inverters.
