This project, a collaboration with Jimmy Xu’s group at Brown, investigated multi-walled carbon nanotube (CNT) Y-junction devices. While the attempts to exploit predicted bandgap changes at the Y-junction did not pan out, we obtained physically interesting results on hopping conduction in CNT material and fabricated three-terminal Y-junction devices.
