Major Academic Achievements

MacDonald's area of interest is on how electron-electron interactions affect electronic properties in condensed matter systems. He previously worked on density functional theory and the Quantum Hall effect, and most recently has focused on the Spin Hall effect, magnetic insulators, magnetic semiconductors and spin-orbit interactions. In a 2011 paper he identified the possibility that the tunnelling energy required for electrons to move between two graphene layers should shrink as the angle between the sheets approaches 1.1 degrees from each other, a prediction that was subsequently proven to be true and has inspired investigations into twistronics. At this angle, bilayer graphene exhibits the property of superconductivity, which could lead to more efficient electric power transmission, levitating trains, cheaper medical imaging (MRI), and more powerful quantum computers.
