Enhanced carrier multiplication in engineered quasi-type-II quantum dots

Carrier multiplication can improve the performance of solar cells, but its efficiency is still not high enough to considerably increase the power output of practical devices. Cirloganu et al.show that appropriately designed core-shell quantum dots can enhance the carrier multiplication yield four-fold.

Sensitive mid-infrared detection in wide-bandgap semiconductors using extreme non-degenerate two-photon absorption

Researchers use extremely non-degenerate photon pairs to achieve two-photon absorption at levels 100-1,000 times that of degenerate two-photon absorption in direct-gap semiconductors. The technique enables the gated detection of sub-bandgap and sub-100-pJ mid-infrared radiation using large-bandgap detectors at room temperature.
