Surface band bending and carrier dynamics in colloidal quantum dot solids

Evidence for band bending in colloidal quantum dot (CQD) solids is shown using photoemission surface photovoltage measurements, and carrier dynamics for a range of CQD solids are measured, correlating the results to surface chemistry.
