Organic field-effect transistors using small-molecule organic single crystals are developed to investigate fundamental aspects of organic thin-film transistors that have been widely studied for possible future markets for 'plastic electronics'. In reviewing the physics and chemistry of single-crystal organic field-effect transistors (SC-OFETs), the nature of intrinsic charge dynamics is elucida...

photocatalytic degradation of toxic organic compound in water, soil and air by semiconductor catalysts such as tio2 and zno have received much attention over the last two decades. however, the low quantum yield, easy agglomeration and difficult post-separation of these inorganic catalysts limit their application for large-scale applications. metal-organic frameworks (mofs) are the latest class ...

Gas sensors based on titanium dioxide (TiO₂) have attracted much public attention during the past decades due to their excellent potential for applications in environmental pollution remediation, transportation industries, personal safety, biology, and medicine. Numerous efforts have therefore been devoted to improving the sensing performance of TiO₂. In those effects, the construct of nanohete...

Polymer transistors are being intensively developed for next-generation flexible electronics. Blends comprising a small amount of semiconducting polymer mixed into an insulating polymer matrix have simultaneously shown superior performance and environmental stability in organic field-effect transistors compared with the neat semiconductor. Here we show that such blends actually perform very poo...

High-performance flexible electronics has attracted much attention in recent years due to potential applications in flexible displays, artificial skin, radio frequency identification, sensor tapes, etc. Various materials such as organic and inorganic semiconductor nanowires, carbon nanotubes, graphene, etc. have been explored as the active semiconductor components for flexible devices. Among th...

Organic and polymeric semiconductor-based thin-film fieldeffect transistors (OFETs) are of great interest for low-cost largearea memories and driving circuits in display applications.1 In these organic devices, the charge carrier transport is dominated by the hopping mechanism at room temperature.2 Therefore, highly ordered thin films with large interconnected polycrystalline grains are necessa...

TIPS-Pentacene, an organic semiconductor characterized by its good electronic properties, solubility, and stability, is used primarily in organic thin-film transistors (OTFT). This research seeks to create an OTFT by crafting a stencil, depositing the source and drain onto a substrate’s surface, and processing TIPS-Pentacene onto the channel between them. In addition, if time permits, the elect...

Electronic coupling between Wannier and Frenkel excitons in an inorganic/organic semiconductor hybrid structure is experimentally observed. Time-resolved photoluminescence and excitation spectroscopy directly demonstrate that electronic excitation energy can be transferred with an efficiency of up to 50% from an inorganic ZnO quantum well to an organic [2,2-p-phenylenebis-(5-phenyloxazol), alph...
