Special Issue Information
Dear Colleagues,
Thin film transistors are a type of field effect transistor made by depositing thin films of an active semiconductor layer, as well as the dielectric layer. There exist a wide variety of applications, such as active-matrix liquid-crystal displays, activematrix organic light-emitting displays, photodetecting devices, and biosensors. Each individual LCD pixel is controlled by one to four transistors. The TFTs acts as an switches which allows the pixels to turn on and off very easily.The basis difference between LCD and TFT is that TFT is technology is used to produce LCDs. Solution processed organic semiconductors have offered potential applications due to their low cost, facile solution process, easy functionalization, mass production, low temperature, large area manufacture, and flexibility. However, conductive polymers have low conductivity and organic materials degrade in moisture, prohibiting suitable application of OTFTs in ambient condition. OTFT have higher on-off ratio, however, suffers from poor field-effect mobility as compared to inorganic semiconductor based thin film transistors.
Recently, new wide-band energy gap semiconductors can be grown by ALD, PLD, sputtering or MOCVD. They have a high potential to fabricate and apply to TFT. The inorganic semiconductors have good stability against environmental degradation over Organic counter parts whereas organic materials are usually flexible, transparent, and solution-processed at low temperatures, they are prone to degradation, when exposed to heat, moisture, and oxygen.
We invite researchers to submit papers that discuss the development of new functional and smart materials inorganic, as well as organic, semiconductor materials such as, ZnO, InZnO, GaO, AlGaO, AnGaO, AlN/GaN, conducting polymers, molecular semiconductors, perovskite based materials, carbon nanotubes, carbon naotubes/polymer composites and 2D materials (for example, grapheme, MoS2), etc., in potential applications for display drivers, radio frequency identification tags, e-paper, gas, chemical and biosensors, etc.
