APCVD Transition Metal Oxides – Functional Layers in "Smart windows"

Growth, characterization and performance of bulk and nanoengineered molybdenum oxides for electrochemical energy storage and conversion

“…solid state thin-film microbatteries [72,173,], electrochemical supercapacitors [194,391], gas sensors [392], electrochromic devices [231], solar cells [393,394], anode interlayers for photovoltaic devices [395], smart windows [396], light-emitting diodes [397], etc. These devices take advantage of the changes in the degree of crystallinity, cationic environment, stoichiometry deviation, band gap energy and electronic conductivity, which can be controlled by the growth conditions.…”

Processing and charge state engineering of MoOx

“…© 2017 Author (s Molybdenum oxide (MoO x ) is a transition metal oxide showing extraordinary electrical, structural, chemical and optical properties, which depend on the oxidation state of Mo, on the degree of crystallinity, on the sample morphology and on environmental conditions. This material system, particularly in the form of thin and ultra-thin films, finds applications in a variety of technologically relevant fields, including catalysis, 1 gas sensors, 2,3 optically switchable coatings, 4,5 high-energy density solid-state microbatteries, 6,7 smart windows technology, 8,9 flexible supercapacitors, 10 thin film transistors (TFTs) 11 and organic electronics. [12][13][14][15][16][17][18][19][20][21][22] Owing to its high work function -up to 6.9 eV [12] and to the layered structure of α-MoO 3 , MoO x is also employed as a 2D material beyond graphene and as efficient hole contact on 2D transition metal dichalcogenides for p-type field effect transistors (p-FETs).…”

Progress and Challenges in Industrially Promising Chemical Vapour Deposition Processes for the Synthesis of Large-Area Metal Oxide Electrode Materials Designed for Aqueous Battery Systems

“…A chemical reaction is initiated in the chamber between the decomposed products and a substrate that causes the precursor gas to react or break down into the desired solid material and bond to the substrate surface in the form of a thin film [ 42 ]. By varying experimental processing parameters such as substrate material, substrate temperature, reaction gas mixture, precursors, and total pressure gas flows, materials with a wide range of properties can be grown [ 43 , 44 , 45 ]. CVD techniques enable the production of coatings with uniform thickness and low porosity even on substrates with complicated shape and patterned surfaces [ 46 ].…”
