Zero-threshold optical gain in electrochemically doped nanoplatelets and the physics behind it
Jaco J. Geuchies, Robbert Dijkhuizen, Marijn Koel +5
Colloidal nanoplatelets (NPLs) are promising materials for lasing applications. The properties are usually discussed in the framework of 2D materials, where strong excitonic effect…

Quantitative electrochemical control over optical gain in quantum-dot solids
Jaco J. Geuchies, Baldur Brynjarsson, Gianluca Grimaldi +4
Realizing solution processed quantum dot (QD) lasers is one of the holy-grails of nanoscience. The reason that QD lasers are not yet commercialized is that the lasing threshold is…

Charge Mobility and Dynamics in Spin-crossover Nanoparticles studied by Time-Resolved Microwave Conductivity
Julien Dugay, Wiel Evers, Ramón Torres-Cavanillas +3
We use the electrode-less time-resolved microwave conductivity (TRMC) technique to characterize spin-crossover (SCO) nanoparticles. We show that TRMC is a simple and accurate mean…
