Abstract

A new approach of chemical bath deposition (CBD) of SnO ₂ thin films is reported. Films with a 0.2 μm thickness are obtained using the multi-dip deposition approach with a deposition time as little as 8-10 min for each dip. The possibility of fabricating a transparent conducting oxide layer of Cd ₂ SnO ₄ thin films using CBD is investigated through successive layer deposition of CBD-SnO ₂ and CBD-CdO films, followed by annealing at different temperatures. High quality films with transmittance exceeding 80% in the visible region are obtained. Annealed CBD-SnO ₂ films are orthorhombic, highly stoichiometric, strongly adhesive, and transparent with an optical band gap of ∼4.42 eV. Cd ₂ SnO ₄ films with a band gap as high as 3.08 eV; a carrier density as high as 1.7 × 10 ²⁰ cm ^-3 ; and a resistivity as low as 1.01 × 10 ^-2 Ω cm are achieved.
