Paper Abstract

We propose an approach to achieve single layer of Si nanodots arrays on insulating layer by using KrF pulsed excimer laser irradiation on ultra-thin hydrogenated amorphous silicon films followed by thermal annealing. Under the suitable fabrication conditions, the area density of formed Si nanostructures can be higher than 1011cm-2 as revealed by AFM images. The size of formed Si nanodots is 3-4 nm for sample with initial a-Si:H film thickness of 4 nm. Room temperature visible light emission can be observed from laser irradiated a-Si:H film after thermal annealing. The results on electron field emission properties were also presented in this paper.
