Properties of cadmium sulphide films grown by single-source metalorganic chemical vapour deposition with dithiocarbamate precursors

Solvothermal synthesis of hexagonal CdS nanostructures from a single-source molecular precursor

“…First of all, it offers the potential advantages of mildness, safety and simplified fabrication procedure and equipment, when compared with the use of multiple sources requiring exact control over stoichiometry, and it is a one-step synthesis compatible with the metallorganic chemical vapor deposition [25][26][27][28][29]. Another important motivation for the utilization of singlesource molecular precursors may be found in the observation of unusual crystal growth selectivity or metastable phase formation of the resultant products, which are sometimes unattainable via the conventional synthesis techniques [18][19][20][21][22][23]30].…”

“…Another important motivation for the utilization of singlesource molecular precursors may be found in the observation of unusual crystal growth selectivity or metastable phase formation of the resultant products, which are sometimes unattainable via the conventional synthesis techniques [18][19][20][21][22][23]30]. The single-source molecular precursors to CdS that have been investigated in this context include Cd(SCNHNH 2 ) 2 Cl 2 [18], [Cd-(DDTC) 2 ] 2 [19][20][21][22], cadmium complexes of N,Ndioctylthiourea, N,N -diocyclohexylthiourea, N,N -diisopropylthiourea, N,N -tetramethylthiourea, dithiobiurea, ethylxanthic acid, thiosemicarbazide, selenosemicarbazide [23], Cd(tta) 2 · tmeda [24], dialkyldithiocarbamate [25,26], bis(diethylmo- nothiocarbamato) cadmium(II) [27], etc. Thermolysis of these precursors in either refluxing organic solvents [18,19,23], porous Vycor glass [20], monosurfactant system [21], gold nanoclustercatalyzed vapor-liquid-solid process [22], nitrogen atmosphere [24] or MOCVD [25][26][27][28][29], etc.…”

“…Among the numerous methods developed for the controllable synthesis of metal chalcogenide materials, the singlesource molecular precursor (an individual reactant molecule containing all the elements required in the final product) route undoubtedly has several appealing features [18][19][20][21][22][23][24][25][26][27][28][29][30]. First of all, it offers the potential advantages of mildness, safety and simplified fabrication procedure and equipment, when compared with the use of multiple sources requiring exact control over stoichiometry, and it is a one-step synthesis compatible with the metallorganic chemical vapor deposition [25][26][27][28][29].…”

Cadmium complex possessing simultaneously silanethiolato- and dithiocarbamato-ligands. A novel single-source precursor of cadmium sulfide

“…Species such as thiolates, dithiocarbamates (dtc) [7][8][9][10][11], dithiophosphinates [12], xanthates [13][14][15], and other compounds [16] have been successfully used to obtain respective sulfides. So far, dithiocarbamates remain most widely used for this purpose with dtc being undoubtedly the one of the most explored S,S 0 -chelate systems.…”

Organometallic and Metallo-Organic Precursors for Nanoparticles

“…The complexes have a wide range of applications in the rubber industry [79], analysis [80] and the petrochemical industry [81]. Dithiocarbamato complexes are air-stable with reasonable volatility and give clean deposition with little carbon incorporation [82]. Thin films of cadmium and zinc sulfide can be prepared by MOCVD under low-pressure conditions (10 -3 -10 -4 Torr, 370-420 • C) using the bis-diethyldithiocarbamato complex of cadmium or zinc [77,83].…”
