Specialized crystalline films revealed to be highly conductive and transparent

The performance of solar cells, flat panel displays, and other electronics are limited by today’s materials. A new material, created by modifying a transparent insulating oxide, replacing up to 25 percent of the lanthanum ions in the host material with strontium ions, offers considerable promise. The new perovskite film, with the formula SrxLa1-xCrO3, (x up to 0.25), conducts electricity more effectively than the unmodified oxide and yet retains much of the transparency to visible light exhibited by the pure material.
