Semiconductor quantum nanostructures for optoelectronic applications

“…[31] They discounted its study in comparison with thicker NPLs due to fundamental physical reasons. 4 In Chapter 6 of this thesis, we have experimentally verified their observations and theoretically studied the exciton dynamics in NPLs of varying thickness to understand how-and-why the electronic bandstructure and polarization dependent excitonic absorption of CdSe NPLs are affected by the thickness dependent quantum confinement.…”

“…Ours is a first account of the theoretical treatment of the anomalous absorption spectral characteristics observed in sub-nanometer (2 ML) CdSe NPLs. 4 Owing to the ultra-strong transversal quantization in 2 ML CdSe NPLs, the exciton wavefunction extends significantly into the neighboring ligand region where the carriers experience a different dielectric environment and effective mass. This affects their electronic structure and exciton dynamics.…”
