Dimethylgold(III) carboxylates as new precursors for gold CVD

Vibrational interactions in dimethylgold(III) halides and carboxylates

“…In the meantime, dimethylgold(III) carboxylates, despite being binuclear molecules, are high volatile compounds and are therefore promising precursors for gold deposition by MOCVD [24,25]. Unfortunately, the data on the structure, spectral properties and chemistry of neutral binuclear Au(III) complexes with organic ligands are still very limited.…”

A low-temperature gold coating of the dielectric surfaces employing phosphine gas as a reducing agent

“…The physical gold coating methods [22][23][24] include vapor deposition, thermal evaporation based on organic compounds of gold and gold vapor condensation on the surface of a product or ion beam or laser sputtering of gold particles. The advantage of physical methods of coatings is the possibility of applying gold directly on the surface of the product, while the disadvantage is the need for expensive and complex installations.…”

Oxygen-free precursor for chemical vapor deposition of gold films: thermal properties and decomposition mechanism

“…To manufacture goldcontaining films, chemical vapor deposition (CVD) is a promising method allowing preparation of conformal coatings on different types of substrates with effective control of morphology of the forming films [9][10][11][12][13]. Thermolysis of the vapors of complex compounds of the metal with organic ligands on a substrate underlies the method of metallorganic CVD.…”

“…Various volatile gold compounds have been investigated as gold CVD precursors. These mainly include substituted phosphine complexes of alkylgold(I) [13,14], trifluorophosphine gold(I) chloride [15], dimethylgold (III) derivatives of β-diketonates [10], carboxylates [11], and salicylaldimines [12]. Dimethylgold(III) β-diketonate derivatives have been the objects of our investigations for a long time: we developed synthesis techniques, established crystal structures, and evaluated the thermal properties of the compounds [16][17][18][19].…”
