Notes:
Nanoparticles of metastable copper nitride(Cu3N) have been successfully fabricated fromCu mask using Ar ion ‘transcription method’ which is firstly invented by B.-S. Xu, C. Iwamoto andS.-I. Tanaka in 1996 [1]. The structural and morphological changes with irradiation time are studiedby transmission electron microscopy (TEM). The thin film-like crystalline Cu3N which is coveredwith amorphous or polycrystalline cuprite (Cu2O) layer in the as-received Cu mask plays a role oftarget. Polycrystalline Cu3N nanoparticles nucleate and grow up to the average size of 15nm after 30sec-irradiation. Coalesence of 50nm-sized grown Cu3N nanoparticles forms polycrystalline thin filmafter 2min-irradiation and its growth behavior follows Volmer-Weber mode. As irradiation timeincreases from 30 sec to 15 min, Cu3N nanoparticles are thought to be grown preferentially along the[111] and [100] directions. Cu2O still remain with Cu3N after 15 min.-irradiation
