Current Research Projects

Our research focses on developing the world's highest-quality systems of carriers in GaAs confined to two or fewer-dimensions within epitaxial barriers. Our work provides samples for many of the leading research labs around the world to investigate the new physics that can be discovered when systems of electrons, or holes, or both, are confined to two or fewer dimensions.
