Sb-Contribution Influence on the Characteristics of Spray-Coated SnO2
Journal Title: Cumhuriyet Science journal - Year 2019, Vol 40, Issue 1
Abstract
This work presents that the impact of Sb-additive on the crystalline, morphological, optical, and electrical features of SnO2. Sb-incorporated samples were fabricated on glass substrates with spray pyrolysis. Pyramidal and polyhedron shaped tetragonal Sb-introduced SnO2 grains were identified with XRD and SEM analysis. The degenerate n-type character for films was determined by electrical and optical characterizations. The resistivity and sheet resistance values initially decreased with Sb-content until 1.5 wt. %, then they increased with further Sb-level. However, carrier concentration increased with 2.5 wt. % Sb-contribution, then it started to goes down with 3.5 wt. %. The optical band-gap values of samples had a decreasing tendency with Sb-doping. From the results obtained in the present study, it is said that Sb-incorporated tin oxide films can be utilized in optoelectronic implements.
