Project title: Transport Dynamics of Nano-networks

Recently there were spectacular progresses in the bottom up approach to nanodevice fabrication based on semiconductor nano-wires. Semiconductor nanowires with diameters as small as several nanometers can be fabricated in laboratories in large quantity. Nano-scale devices such as field effect transistors and p-n diodes can be built from these nano-wires. Integration of these nano-devices is possible by constructing a nano-wire cross-network. This will have significant impact on microelectronic technology. There are already some theoretical studies of the static characteristics of these nano-devices. It is therefore important to study the transport dynamics of nano-wire network so as to understand the operation speeds of nano-wire integrated circuits. In this project, a theoretical study of how fast charges can move in a nano-wire network will be carried out using classical and quantum transport theory. Results obtained will be very useful for the development of nano-wire integrated systems.
