Tight-binding calculations of image-charge effects in colloidal nanoscale platelets of CdSe
Tight-binding calculations of image-charge effects in colloidal nanoscale platelets of CdSe
CdSe nanoplatelets show perfectly quantized thicknesses of a few monolayers. They present a situation of extreme, yet well defined quantum confinement. Due to a large dielectric contrast between the semiconductor and its ligand environment, interaction between carriers and their dielectric images strongly renormalize bare single particle states. We discuss the …
