In this paper, we demonstrate enhanced field emission properties from MWNT emitters grown directly on the 80/20 NiCr alloy surface due to the grain boundary effect. The elemental segregation was clearly demonstrated by AES elemental mapping, where Cr and O surface segregation inhibited MWNT growth. The potential for this simple process is that it may be employed for fabricating CNT emitters without...
