Surface doping of nanostructures
Abstract
This disclosure provides systems, methods, and apparatus related to surface doping of nanostructures. In one aspect a plurality of nanostructures is fabricated with a solution-based process using a solvent. The plurality of nanostructures comprises a semiconductor. Each of the plurality of nanostructures has a surface with capping species attached to the surface. The plurality of nanostructures is mixed in the solvent with a dopant compound that includes doping species. During the mixing the capping species on the surfaces of the plurality of nanostructures are replaced by the doping species. Charge carriers are transferred between the doping species and the plurality of nanostructures.
