submitted by: thenatureexplorers

Located on the Arizona and California border along the southern Colorado River, the river provides an oasis in arid desert to the migrating birds flying south along the Pacific Flyway to Central and South America and is a habitat as well for many other animals such as feral donkeys, raccoons, lizards, chipmunks, and more.

Making Most of the Absorbed Photon: New Insights into Carrier Multiplication in Semiconductor Nanostructures

submitted by: RASEIBoulder
Carrier multiplication (CM) or multiexciton generation (MEG) is a process whereby absorption of a single photon produces multiple electron-hole pairs (excitons). CM could benefit a number of solar-energy conversion technologies, most notably photocatalysis and photovoltaics. This presentation overviews recent progress in understanding of the CM process in semiconductor nanocrystals, motivated by an outstanding challenge in this field - the lack of capability to quickly discern between...
