Controlled semiconductor nanorod assembly from solution: influence of concentration, charge and solvent nature

Controlled semiconductor nanorod assembly from solution: influence of concentration, charge and solvent nature

Spontaneous supercrystal organisation of semiconductor nanorods (CdS and CdSe) of different aspect ratios into ordered superstructures was obtained by controlled evaporation of ananorod solution. The rods either align into two dimensional close packed perpendicular arrays or into one dimensional rail tracks depending on the total interaction energy between the rods in solution. A detailed study has identified critical factors that affect […]
