Colloidal Nanoplatelets Act Like Quantum Wells
The relaxation of high-energy carriers (electrons and holes) in colloidal nanoplatelets have been measured by researchers in the Nanophotonics Group at Argonne National Laboratory, working with colleagues at the Univ. of Chicago. The measurements show that the carriers behave like carriers in quantum wells. Quantum wells have found widespread application in optoelectronics, and the new results suggest that colloidal nanoplatelets should find similar applications, with the added advantage that they can be produced at low cost and in large quantities.
