Field emission of comb-like chromium disilicide nanowires prepared by an in situ chloride-generated route
Large-area comb-like chromium disilicide (CrSi 2 ) nanowire film has been successfully synthesized on silicon wafer through an in situ chloride-generated route. The sample possesses branch-like nanowires grown out perpendicularly and evenly from both sides of a stem-like microrod, forming 2-fold com...
