Abstract

An efficient deposition method for colloidal nanoparticles (NPs), Langmuir-Blodgett (LB) deposition is investigated and used to fabricate close-packed arrays of silicon (Si) NPs. Both amorphous and ordered arrays are achievable by tuning the stabilizing time and surface pressure (SP) of the LB film on the surface of water in the LB procedures. The deposited NP layers were characterised by AFM and TEM. AFM observation showed successful formation of monolayers, while TEM results clearly showed the orientations of the arrays. Such arrays might be used as the absorber materials of hot carrier solar cells because of their potential for strong phonon confinement [1].
