The effects of Argon plasma on the morphology and crystal structures of nanoflakes were investigated. Significant enhancement of field-induced electron emission from the plasma-treated nanoflakes was observed. The transmission electron microscopy investigation shows that the plasma treatment effectively removes amorphous coating and creates plenty of sub-tips at the surface of the nanoflakes, which are believed to contribute the enhancement of emission. This work suggests that plasma treatment technique could be a direct means to improve field-emission properties of nanostructures. © to the authors 2009. | Source Title: | Nanoscale Research Letters | URI: | http://scholarbank.nus.edu.sg/handle/10635/86302 | ISSN: | 19317573 | DOI: | 10.1007/s11671-009-9363-1 |
