Abstract:
For modern electronics, large arrays of solution processable and high performance materials are in a strong demand. Despite the significant importance of solution processed logic circuits for RFID tag, there is no research projects related to the development of solution processable self-assembled semiconductors for large area device application and integration in Hong Kong. This project explores a unique and simple way to fabricate a solution processable logic circuit for RFID tags. We will fabricate self-assembly metal and metal oxide colloidal nanoparticles with p-type and n-type semiconducting properties. Using solution process technique, thin film made from the arrays of p-type and n-type colloidal metal and metal oxide nanoparticles transistors (TFTs) will be fabricated. In
addition, solution processable logic circuit based radio-frequency identification (RFID) tags consisting of many TFTs will be achieved. This project paves a way for fabricating RFID tags through a simple self-assembly process approach.

Title: Inexpensive Materials for Flexible Transistors and Inverters
Abstract:
Since the report of the first organic thin film transistor (OTFTs) in 1986, there have been great progresses in both the materials performance and development of new fabrication techniques. OTFTs have great potential for a wide variety of applications, especially for new products that rely on their unique characteristics, such as electronic newspapers, inexpensive smart tags(http://www.organicid.com). and large-area flexible displays (http://www.plasticlogic.com). In this proposal, the first deliverable is to achieve high performance OTFTs based on inexpensive charge transfer (eT) complexes. We will demonstrate solution-processed ambipolar thin film transistors (TFTs) where the hole and electron can be transported in a single layer. From our preliminary results, ambipolar transport is observed in CT based complexes. Despite the significant importance of OTFT research area, there is no such research project related to the development of charge transfer materials for OTFT applications in Hong Kong. The principal and co-investigators will demonstrate the basic material requirements and simple fabrication techniques for building inexpensive practical OTFT devices.

Deliverables:
1. Nickel based ion-pair charge transfer complexes for solution processed OTFTs that possess ambipolar transport properties with balanced electron and hole mobilites.
2. Inexpensive materials for OTFT devices that exhibit low voltage device operation (up to 3V), almost negligible hysteresis and high
on/off ratio (10^5).
3. Prototype organic RFID with inverters having gain up to 15 with low noise margin ratio (at least 1/3 of the supply voltage).
4. Patent will be filed on organic thin film transistors, inverters and RFID based on Nickel complexes.
