Laser cooling of a semiconductor by 40 kelvin: an optical refrigerator based on cadmium sulfide nanoribbions
We have demonstrated the first net laser cooling of semiconductors using CdS nanoribbons (or nanobelts) in this work. This net cooling effect is found to be facilitated by resonant high order annihilation of longitudinal optical (LO) phonons due to a strong exciton-LO phonon Fröhlich interactions. U...
