Self-assembly Nanoparticles for RFID Tag

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..
