研究目的

Describing the production of SenS8?n thin film via chemical dropping method and examining structural, optical and electrical properties of the produced thin films.

研究成果

Selenium sulfide (SeS2) crystalline thin films were produced via chemical bath deposition on commercial glass substrates. By changing the concentration of SeS2, four different thin films were produced and their optical properties were examined. Up to 0.004 M concentration, thin films displayed high optical transmittance and had low reflectivity. When the concentration of the solution exceeded 0.005 M, these optical values changed dramatically. Similar concentration-dependent behavior was also observed for n, k, ε values and absorbance. These parameters were examined in detail within the visible region. For the samples with 0.002 M and 0.003 M concentration, dielectric constant values were found to be greater than unity and high transmittance properties were observed for samples with a concentration 0.003 M and below. SeS2 thin films deposited in lower concentration can be produced easily via chemical bath and can be used as a transparent layer for different optical applications.

研究不足

The study focuses on the optical properties of selenium sulfide thin films produced via chemical dropping method, but does not explore other production methods or the scalability of the process.
