Organic–inorganic hybrid perovskite single-crystalline thin films (SCTFs) are promising for enhancing photoelectric device performance due to high carrier mobility, long diffusion length, and lifetime. However, bulk single crystals available today not suitable practical application the unfavorable thickness. Herein, we report a facile space-confined solution-processed strategy on-substrate grow various SCTFs in size of submillimeter with adjustable thicknesses from nano- micrometers. These...
Low-threshold two-photon-pumped (TPP) perovskite microcavity lasers are achieved in crystal 1D or 2D microstructures fabricated through a liquid-phase self-assembly method assisted by two distinct surfactant soft templates. The lasing actions from the materials exhibit shape-dependent effect, which is subsequently utilized for modulation of modes and achievement single-mode microlasers.
Abstract Self-assembly of monolayers functional molecules on dielectric surfaces is a promising approach for the development molecular devices proposed in 1970s. Substrate chemically bonded self-assembled semiconducting conjugated exhibit low mobility. And monolayer crystals are difficult to scale up and limited growth substrates terminated by hydroxyl groups, which makes it realize sophisticated device functions, particularly those relying n-type electron transport, as electrons suffer...

Optoelectronic devices based on metal halide perovskites, including solar cells and light-emitting diodes, have attracted tremendous research attention globally in the last decade. Due to their potential achieve high carrier mobilities, organic-inorganic hybrid perovskite materials can enable high-performance, solution-processed field-effect transistors (FETs) for next-generation, low-cost, flexible electronic circuits displays. However, performance of FETs is hampered predominantly by...
Abstract It is generally believed that the photoresponse behavior of organic field‐effect transistors (OFETs) reflects intrinsic property semiconductors. However, this hinders application OFETs in transparent displays as driven circuits due to current instability resulting from threshold voltage shift under light illumination. necessary relieve photosensitivity keep devices stable. 2,6‐diphenyl anthracene thin‐film and single‐crystal are fabricated on different substrates, it found degree...
