Abstract

Honeycomb structured copper indium sulfide layers are successfully realizedviaa nanosphere lithography route employing polystyrene nanosphere array templates and metal xanthates or a nanocrystal ink.

Highlights

  • The major structuring techniques are based on templates

  • The polystyrene nanosphere (PS-NS) templates were prepared with an air/liquid interface method using a suspension of the PS-NS in a water/ethanol mixture

  • A glass slide is placed in the centre of a Petri dish, an amount of the suspension is dropped on the glass slide and subsequently water is slowly added until the PS suspension is rapidly spread on the air/water interface, leading to the two-dimensional (2D) layer assembly

Summary

Introduction

The major structuring techniques are based on templates. There are two templating strategies, namely hard-templating or nanocasting routes, and soft-templating. Novel thioglycerol-capped CuInS2 nanocrystals (NCs) were synthesised, characterized and employed for the formation of honeycomb-structured thin films.
