Localization-limited exciton oscillator strength in colloidal CdSe nanoplatelets revealed by the optically induced stark effect

open access: yesLight: Science & Applications, 2021
2D materials are considered for applications that require strong light-matter interaction because of the apparently giant oscillator strength of the exciton transitions in the absorbance spectrum. Nevertheless, the effective oscillator strengths of these

Structural selective charge transfer in iodine-doped carbon nanotubes [PDF]

open access: yes, 2006
We have investigated iodine intercalated carbon nanostructures by extended X-ray absorption fine structure (EXAFS) and Raman spectroscopies. We discuss here the charge transfer and the iodine–carbon interaction as a function of the carbon nanostructures (

DNA-based self-assembly of chiral plasmonic nanostructures with tailored optical response [PDF]

open access: yesNature, 2011
Matter structured on a length scale comparable to or smaller than the wavelength of light can exhibit unusual optical properties. Particularly promising components for such materials are metal nanostructures, where structural alterations provide a ...

Interaction-induced hopping phase in driven-dissipative coupled photonic microcavities

open access: yesNature Communications, 2016
Coupled semiconductor microcavities constitute a model system where the hopping, interaction, and decay of exciton polaritons can be engineered. Here, Rodriguez et al.

Assessment of the notions of band offsets, wells and barriers at nanoscale semiconductor heterojunctions [PDF]

open access: yes, 2011
Epitaxially-grown semiconductor heterostructures give the possibility to tailor the potential landscape for the carriers in a very controlled way. In planar lattice-matched heterostructures, the potential has indeed a very simple and easily predictable ...

Deterministic radiative coupling of two semiconductor quantum dots to the optical mode of a photonic crystal nanocavity

open access: yesScientific Reports, 2017
A system of two site-controlled semiconductor quantum dots (QDs) is deterministically integrated with a photonic crystal membrane nano-cavity. The two QDs are identified via their reproducible emission spectral features, and their coupling to the ...
