Research Abstract

Device structures and measurement systems were developed for optical detection of spins in single-walled carbon nanotubes. To enable electrical spin injection and optical detection on individual nanotubes, field-effect transistors that utilize suspended carbon nanotubes have been fabricated. In addition, we have constructed a laser scanning confocal photoluminescence microscopy system with capabilities for low temperatures measurements in static magnetic fields and microwave fields.
