Pulsed electrodeposition and characterisation of tungsten diselenide thin films

Hexagonal nanosized molybdenum diselenide thin film deposited at 333 K by chemical method

“…The lattice parameters 'a and c' of MoSe 2 film were found to be a ¼ 3.246 and c ¼ 12.674 Å respectively. These values are in good agreement with the earlier reported value [19,20]. The average crystallite size was calculated by resolving the highest intensity peak using Scherrer formula.…”

Structural, optical and microscopic studies of tungsten substituted molybdenum diselenide thin films

“…Most of the TMDC compounds studied can be considered structurally as strongly bonded two-dimensional X-M-X (M = metal, X = chalcogen) layers loosely coupled to one another by relatively weak van der Waals type forces [1][2][3][4]. Recent investigations have shown that the layered type semiconducting group VI transition metal dichalcogenides, which absorb visible and near-IR light are particularly interesting materials for photoelectrochemical solar energy conversion.…”

Cathodic electrodeposition of mixed molybdenum–selenium oxides

“…In recent years, the electrodeposition of metal alloys and mixed metal oxides from aqueous solutions has attracted the interest of several investigators [3,23,24]. While the electrodeposition of metal oxides and dichalcogenides such as MoO 2 , MoSe 2 , MoS 2 , and WSe 2 , have been reported, the majority of these studies are performed in high pH electrolyte solutions [20,[25][26][27]. In contrast, very few reports have described the electrodeposition of metal oxides and metal chalcogenides from acidic solutions [28,29] since alkaline conditions offer significantly less hydrogen generation and ability to move the electrodeposition potentials of metallic elements closer together [30].…”
