Exciton diffusion and dissociation in organic and quantum‐dot solar cells

open access: yesSmartMat, 2023
For the process of photovoltaic conversion in organic solar cells (OSCs) and quantum‐dot solar cells (QDSCs), three of four steps are determined by exciton behavior, namely, exciton generation, exciton diffusion, and exciton dissociation.

Naturally-meaningful and efficient descriptors: machine learning of material properties based on robust one-shot ab initio descriptors

open access: yesJournal of Cheminformatics, 2022
Establishing a data-driven pipeline for the discovery of novel materials requires the engineering of material features that can be feasibly calculated and can be applied to predict a material’s target properties.

Active waveguide Bragg lasers via conformal contact PDMS stamps

open access: yesScientific Reports, 2022
Lasing is observed in Bragg lasers formed through conformal contact of a patterned PDMS stamp with a plain active film, spincoated on glass. The thresholds, output efficiencies and spectral characteristics are compared to standard substrate patterned ...

NV-plasmonics: modifying optical emission of an NV− center via plasmonic metal nanoparticles

open access: yesNanophotonics, 2022
The nitrogen-vacancy (NV) center in diamond is very sensitive to magnetic and electric fields, strain, and temperature. In addition, it is possible to optically interrogate individual defects, making it an ideal quantum-limited sensor with nanoscale ...
