“…showed the structural parameters, the results showed that the film had a good crystalline in tetragonal structure and the intensity increased with the increasing of the thickness [24,25,26] with a simple shift at the distinctive peaks. This was due to the different conditions of preparation of the In parliamentary law, to examine the surface topography, roughness of thin films and the impression of film thickness on it, we used the atomic force microscope (AFM), which possessed the ability to get very precise statistical values about the texture size and surface roughness values depending on the root mean square (r.m.s.).…”

CuAlTe2 thin films were evaporation on glass substrates using the technique of thermal evaporation at different range of thickness (200,300,400and500) ±2nm. The structures of these films were investigated by X-ray diffraction method; showing that films possess a good crystalline in tetragonal structure. AFM showed that the grain size increased from (70.55-99.40) nm and the roughness increased from (2.08-3.65) nm by increasing the thickness from (200-500) nm. The optical properties measurements, such as absorbance, transmtance, reflectance, and optical constant as a function of wavelength showed that the direct energy gap decreased from (2.4-2.34) eV by the gain of the thickness.

“…25,33 Thin films of CuAlS 2 have been applied as a transparent p-type contacts in CIGS and organic solar cells, 33,92 but the material has otherwise received relatively limited attention in the literature. Despite the smaller number of studies, CuAlS 2 has been synthesized by a wide variety of deposition techniques, including solution-based techniques, such as CBD, 33,93 CVD methods, such as atomic layer deposition (ALD) and MOCVD, 91,92,94 solid-state synthesis routes, 25 thermal evaporation or sulfurization, [95][96][97][98] and even spray pyrolysis. 99,100 One important finding from these investigations is Cu-rich composition leading to higher conductivity, 26,33 due in part to the VB shifting upward with increasing copper content.…”

Transparent conductive materials (TCMs) with high p-type conductivity and broadband transparency have remained elusive for years. Despite decades of research, no p-type material has yet been found to match the performance of n-type TCMs. If developed, the high-performance p-type TCMs would lead to significant advances in a wide range of technologies, including thin-film transistors, transparent electronics, flat screen displays, and photovoltaics. Recent insights from high-throughput computational screening have defined design principles for identifying candidate materials with low hole effective mass, also known as disperse valence band materials. Particularly, materials with mixed-anion chemistry and nonoxide materials have received attention as being promising next-generation p-type TCMs. However, experimental demonstrations of these compounds are scarce compared to the computational output. One reason for this gap is the experimental difficulty of safely and controllably sourcing elements, such as sulfur, phosphorous, and iodine for depositing these materials in thin-film form. Another important obstacle to experimental realization is air stability or stability with respect to formation of the competing oxide phases. We summarize experimental demonstrations of disperse valence band materials, including synthesis strategies and common experimental challenges. We end by outlining recommendations for synthesizing p-type TCMs still absent from the literature and highlight remaining experimental barriers to be overcome.
