LOS ALAMOS, N.M., Jan. 25, 2006 -- Los Alamos National Laboratory scientists have discovered that a phenomenon called carrier multiplication, in which semiconductor nanocrystals respond to photons by producing multiple electrons, is applicable to a broader array of materials than previously thought. The discovery increases the potential for the use of nanoscrystals as solar cell materials to produce higher electrical outputs than current solar cells. In papers published recently in the journals Nature Physics and Applied Physics Letters, the scientists demonstrate that carrier multiplication...Read full article
