Data-Driven Gas Sensing Analysis of Tin Sulfide Films Modified with Copper
Hayim Ch. Magid, Muna Ahmed Issa, Z. M. Shabanb, Shaymaa A. Hussein, Sami Salman Chiad, Nadir Fadhil Habubi and Yassin Hasan Kadhim Abstract: Considerable attention was paid to the physical characteristics of SnS:Cu thin films produced by plasma jet technique at different argon flow rates of 0.5, 1, and 1.5 L/min. According to XRD patterns, the grown films are cubic polycrystalline with a dominating peak at the (115) plane. The investigation guarantees that the structure and dominating peak were unaffected by varying the flow rate. The XRD profile shows an increase in grain size (nm) from 11.25 nm to 12.36 nm as the argon flow rate increases. Similarly, the strain decreased from 30.81 x 10-4 to 28.04 x 10-4 with increasing flow rate. Using atomic force microscopy, the average particle size was determined to be between 88.1 and 42.3 nm, while the average roughness was between 10.69 and 3.26 nm. SEM analysis of films prepared at different flow rates revealed distinct trends. Films prepared at 0.5 L/min exhibited higher aggregation and a more homogeneous structure. Whereas those prepared at 1-1.5 L/min showed increased porosity. In Vis-NIR areas, the transmission values of the films exceed 75%. The absorption coefficient increased with increasing argon flow rate, while the optical energy gap values decreased from 1.42 eV to 1.30 eV. Additionally, optical constants decreased as the flow rate increased. SnS:Cu films show decreased resistance with higher argon flow, indicating improved crystallinity, surface uniformity, and enhanced charge carrier mobility. SnS:Cu films show decreasing NO₂ sensitivity with higher argon flow rates.
