Welcome!
Welcome to the
Advanced Materials for Energy and Electronics Group! We are a vibrant
team of graduate and undergraduate students and postdoctoral researchers directed by Professor Michael
Arnold of the Department of Materials Science and Engineering at UW-Madison. Our group
researches and develops promising materials at the extreme limit of matter for future information technology, energy,
environment, and biotechnology applications.
Materials
The group has a current focus on materials including:
- Carbon nanotubes - seamless cylinders of carbon only one billionth of a meter in diameter
- Atomically thin sheets of graphene
- Two-dimensional materials
- Semiconducting molecules and polymers and
- Heterostructures that integrate these components with conventional, macroscopic materials
Impact
In the ultrathin limit, new electronic and optoelectronic phenomena arise, materials become
dramatically more mechanically resilient and deformable, and the flow of electrical charges and molecules can be more
precisely controlled and sensitively detected. Our research aims to take advantage of these properties in order to realize
transformative gains in:
- Integrated circuits - higher-performance computer chips that extend Moore's law and consume less power
- Communication technologies - lower power and higher bandwidth circuits for wireless communication devices
- Unconventional electronics - circuits that can be folded, stretched, and integrated on clothing or skin
- Solar cells and photodetectors - that are based on novel materials and that are more efficient and sensitive
- Artificial materials - that rapidly and efficiently funnel energy in a fashion that mimics plants and bacteria
- Sensors - More sensitive and selective devices for detecting biological and environmental factors
- Chemical separations - Selectively permeable membranes for separating molecules (e.g. for water desalination) that are substantially thinner and more structurally precise than any existing membrane and thus dramatically more permeable, efficient, selective, and functional.
Challenges
The impact of nanomaterials on society is limited because they're difficult to synthesis,
purify, process, organize, and integrate into nanostructures. Our research draws from multiple disciplines to address fundamental materials challenges - in
understanding phenomena beyond the scale of single nanostructures - that must be overcome to exploit these exciting materials
in technology.
