Size-quantized semiconductor particles formed at monolayer surfaces

Abstract

Infusion of H₂S onto cadmium arachidate, zinc arachidate, or metal-ion-coated poly(styrenephosphonate diethyl ester) monolayers resulted in the formation of size-quantized semiconductor particles which could be transferred, essentially intact, to solid substrates at different stages of their growth; scanning tunnelling microscopy, transmission electron microscopy, and absorption spectrophotometry established the initial formation of 25–30 Å diameter particles which aligned themselves and grew laterally to linked, 50–100 Å diameter, 20–30 Å thick, disk-shaped polyparticles.
