MTorrice writes: To build components for flexible electronics, some engineers have turned to thin films made from semiconductor nanocrystals. Unfortunately, many of these nanomaterials lose their unique electronic properties when exposed to air or solvent, making them incompatible with large-scale fabrication methods. Now researchers report that treating the films with indium can fix the problem. The treatment could move nanocrystal-based electronics out of the lab and into commercial applications, the researchers say, leading to low-cost, flexible electronics such as solar cells and displays.
