CuO nanowires for inhibiting secondary electron emission

Abstract

Copper oxide nanowires (NWs) grown on copper to avoid the secondary electron emission were investigated. Optimal temperatures for NW growth were found to be in the range 700–800 K. NW surface coverage of 102 µm−2 is required to strongly reduce the secondary electron yield. A total secondary electron emission coefficient below 1 was obtained for NW aspect ratio higher than 103. © 2013 IOP Publishing Ltd.
