Abstract
Colloidal semiconductor nanocrystals are excellent systems
for exploring the fundamental properties of quantum-confined
charge carriers. Tremendous progress has already been made
in understanding the properties of electron-hole pairs (excitons)
confined in colloidal quantum dots (QDs) using optical spectroscopic
techniques.1-6 In contrast with charge carriers in QD
electronic excited states, the properties of QDs containing excess
carriers in their ground states have received substantially less
attention.7-19 To date, the primary experimental probe of such
charged QDs has been electronic absorption spectroscopy, in
which low-energy intraband excitations can be used to define
the carrier wave function.
