Nanocomposite Materials Fabrication and Characterization
Advanced VLSI processing has provided unparallelled control in creating minute patterns over the last 40 years. Such technology has made significant contributions to analog and digital circuit and photovoltaic applications. It is the premise of this research that energy storage devices can likewise benefit from this technology as it advances over the next 15 years. Unlike current battery technologies, new transformational energy storage devices need to be lightweight, long lasting, and fast charging with high power delivery capabilities. The objective of this research is to construct capacitive storage devices that push the energy density limits of metal-insulator nanocomposite materials in order to better study and understand how this technology can impact our society. This work will capitalize on experiments performed over the last 30-40 years that reported that under certain conditions nanocomposite materials can have an anomalous dielectric effect that produces extremely high dielectric constants. The goal of this research is to produce a unified theory to explain this phenonomem and to produce prototype devices by creating reproducible and homogeneous samples of these nanocomposite materials using e-beam lithography.
The goal of this work is to get Georgia students exciting about engineering. It is also to help students understand how to work in teams and how to solve complex problems. To this end, Dr. Davis helps to organized a FIRST LEGO League State Finals robot competition every year at Georgia Tech. He also participates in various summer camps over the summer for high school students to accomplish the same goal.
