Surface Morphology, Roughness, and Structural Characteristics of Al1−xMgxSb (x = 0 and 0.1) Thin Films Deposited by Chemical Bath Deposition Technique

Abstract

Aluminum antimonide (AlSb), a semiconductor compound, finds its applications in optoelectronics because of its tunable bandgap and promising properties achieved by tailoring suitable dopants. To explore the effects of doping, thin films of pure AlSb and 10% magnesium (Mg)-doped aluminum antimonide (MgAlSb) were synthesized through compound solution deposition on a glass substrate using a low-cost chemical bath deposition (CBD) technique at varying bath temperatures with deposition time intervals ranging from 60 to 180 min. Optical microscopy was used to evaluate the surface roughness and morphology of the synthesized films, revealing the surface roughness and thin film uniformity at different deposition times. The structural characteristics of AlSb and Mg-doped AlSb thin films were further examined using the X-ray diffraction technique, which validated the formation of AlSb and Mg-doped AlSb thin films. This research enables large-scale low-temperature deposition for a variety of conceivable applications in the coatings, materials penetration, energy, and photonic sectors due to the novel properties of this material.

Effect of Deposition Time on the Properties of NiS Films Prepared by Chemical Bath Deposition

“…Mohammad Gomma et al, synthesized NiS 2 nanoflake layers on a glass substrate by chemical bath deposition method followed by sulfurization process and reported the crystallite size was 26 nm, and optical properties showed a band gap of 1.19 eV (6) . In CBD, the deposition time is one of the most important factors that affect the release of anions and cations in a reaction bath, which leads to a phase change and variation in grain size along with surface roughness (15) . The variation in deposition time is also one of the key factors in the CBD process to know the optimum condition for the synthesis of the material.…”
