We investigate the formation of the irregular sidewall and halo of pillars grown by ion-beam-induced deposition (IBID) by,growing platinum nanopillars on an insulating Si(3)N(4) membrane and on a semiconducting Si wafer with a thin Si3N4 top layer. As compared with the pillars grown in a conductive environment, the pillars grown on an insulating membrane are smoother, higher and thinner but have the same volume. Furthermore. they arc accompanied by smaller halos. These differences Suggest a distinct charging effect in IBID pillar growth. This charging effect is attributed to the secondary electron emission and possibly the aggregation of precursor gas molecules. [DOI: 10.1143/JJAP.47.8120]
