Unraveling Size Dependent Bi- and Tri-exciton Characteristics in CdSe/CdS Core/Shell Quantum Dots via Ensemble Time Gated Heralded Spectroscopy
Einav Scharf, Rotem Liran, Adar Levi +4
Multiexcitons (MXs) in quantum dots (QDs) manifest many body interactions under quantum confinement. Beyond this fundamental interest, MXs are of importance in numerous optoelectro…
Photon Correlations in Colloidal Quantum Dot Molecules Controlled by the Neck Barrier
Somnath Koley, Jiabin Cui, Yossef. E. Panfil +5
We investigate the charge re-distribution upon optical excitation of various necked homodimer CQDMs using single particle emission spectroscopy. By tuning the hybridization of the…
Two Biexciton Types Coexisting in Coupled Quantum Dot Molecules
Nadav Frenkel, Einav Scharf, Gur Lubin +7
Coupled colloidal quantum dot molecules are an emerging class of nanomaterials, introducing new degrees of freedom for designing quantum dot-based technologies. The properties of m…
Electric field induced color switching in colloidal quantum dot molecules at room temperature
Yonatan Ossia, Adar Levi, Yossef E. Panfil +6
Colloidal semiconductor quantum dots are robust emitters implemented in numerous prototype and commercial optoelectronic devices. However, active fluorescence color tuning, achieve…
