摘要

Three-dimensional (3D) nanostructured Sn_2S_3 semiconductor films have been prepared on ITO-coated glass substrates by potentiostatic electrodeposition at -0.80 V (vs. SCE) from a novel plating bath containing K_4P_2O_3 as a complexing agent and Na_2SO_3 as a stabilizing agent and by subsequent annealing. Results showed that the annealing drove the as-deposited Sn_2S_3 films to grow from a granular structure into a nanorod network structure. The nanorods were around 50-100 nm in diameter and 1000 nm in length. The band gap of the annealed film was 1.65 eV and the conductivity was n type. The carrier mobility achieved up to 20.5 cm2 V~(-1) s~(-1) due to the direct electrical pathways provided by the nanorod network.
