Summary: The single-electron properties of a self-assembled metal nanodot array film attached to multiple gates were investigated in this study. The results showed that the charge state of the single dot in the nanodot array can be controlled by both the top- and bottom-gate voltages, and the geometric effects caused uneven influences on the electronic state of the dot. These findings are important for enhancing the functionality of multidot devices.

Summary: Narrow-bandgap Sn-Pb mixed perovskite single crystals show great potential as photoactive materials for efficient and low-cost near-infrared (NIR) photodetectors. However, the phase separation issue during crystallization process leads to the degradation of optical and electronic properties. In this study, a low-temperature space-confined technique (LT-SCT) is proposed to reduce the crystallization velocities and create pure-phase (FASnI(3))(0.1)(MAPbI(3))(0.9) single crystals. These crystals exhibit excellent crystallinity, high hole mobility, and low surface trap density, enabling their application in self-powered NIR photodetectors with outstanding performance. The work contributes to the development of Sn-Pb mixed perovskite single crystals and offers a promising candidate for efficient and low-cost NIR photodetection.

Summary: The development of a simple double-blade-coating printing technique using wetting-patterned substrates allows for the production of highly crystalline organic semiconductor (OSC) thin films. This method significantly reduces the number of nucleation events, resulting in thin films with single-crystal domains and high yield. The organic field-effect transistor array fabricated from these patterned OSC thin films exhibits excellent performance with an average mobility of 11.5 cm(2) V-1 s(-1), which is 12.5-fold higher than the reference sample fabricated using conventional single-blade coating. This approach has the potential to be widely applied to other soluble organic materials, enabling the fabrication of multicomponent integrated electronics.

Summary: In this study, we designed a multifunctional small-molecule hole-transporting material (HTM) called X10 for use in perovskite quantum dot light-emitting diodes (Pe-QLEDs). X10 exhibited high hole mobility, good film-forming ability, strong solvent resistance, and defect passivation effect. Pe-QLEDs using X10 as the HTM achieved a promising external quantum efficiency (EQE) of 20.18%, which was 7-fold higher than that of reference HTM-TCTA-based ones (EQE approximately 2.88%). This is the first case where a small-molecule HTM has shown a high EQE over 20% in Pe-QLEDs. Our work provides important guidance for the rational design of multifunctional small-molecule HTMs for high-performance Pe-QLEDs.
