Coherently driven microcavity-polaritons and the question of superfluidity
If particles of light (photons) are trapped in a two dimensional cavity, then they can couple electron-hole pairs present in semiconductors in the cavity. The resultant composite particles, which we call polaritons, flow like fluids do and can exhibit quantum...
Efficient Near-infrared Electroluminescence from a “Metal-Free” Fluorophore
Burgeoning interest for near-infrared (NIR) organic light-emitting diodes (OLEDs) is fuelled by the huge prospects for integration in a broad range of applications, spanning from “biomedics” (for sensing, bio-imaging, photodynamic therapy, optogenetics, to name just a...
Photocatalysis: Importance of the Aqueous Interface
The interaction of water on TiO2 is crucial to elucidate photocatalytic water splitting for hydrogen fuel generation. Anatase and rutile are the most commonly occurring polymorphs of TiO2. Although the interaction of water on rutile surfaces has been extensively...
Perovskite solar cell technology for exceptional light harvesting under indoor illumination
Perovskite solar cells have been attracting great attention from the scientific and industrial communities in the past few years because they are able to combine high power conversion efficiencies under standard test conditions (i.e. those of the sun) with simple...
