The studies on the synthesis of two-dimensional (2D) Janus materials have made significant progress over the years. They offer new opportunities to increase the potential usage of Janus transition metal dichalcogenide (TMDC) materials in different application areas due to their unique structural, electrical, optical and mechanical properties. However, the difficulties in synthesizing these materials stand out as a critical factor for further research in this field. This manuscript aims to provide a comprehensive overview of this rapidly developing field by reviewing studies in which Janus TMDC structures have been experimentally obtained. Within the scope of the research, the synthesis methods such as chemical vapor deposition (CVD), pulsed laser deposition (PLD), selective epitaxial atomic replacement (SEAR), plasma-assisted selenization process (PASP) and room temperature atomic layer selenization (RT-ALS) have been handled in detail. The analysis results obtained by various characterization methods such as Raman spectroscopy, photoluminescence (PL), atomic force microscopy (AFM), Kelvin probe force microscopy (KPFM), transmission electron microscopy (TEM), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), piezoelectric properties, mechanical properties and second harmonic generation (SHG) have been looked into. Moreover, the kinetic mechanisms of the synthesis processes have been particularly discussed so that the synthesis processes of the materials can be optimized and more controlled synthesis techniques can be developed. As a result of literature review, we can conclude that Janus TMDC structures should have a much wider range of applications despite the difficulties in their synthesis and novel strategies should be developed to synthesize new kind of Janus materials.
