We used vanadium oxide as thermistor material for MEMS style calorimeter arrays, see a.o. http://ieeexplore.ieee.org/xpls/abs_all.jsp?arnumber=4300493 There are many different vanadium oxides (and phases) and ways of depositing thin films of it. We deposited vanadium pentoxide by reactive sputtering of vanadium in a mixed argon/oxygen environment. More info in the paper; or do a search and follow the links in Google Scholar to more of our publications. It is easily patterned by wet etching (try a solution of hydrogen peroxide), or lift-off. Dirk De Bruyker Palo Alto Research Center -----Original Message----- Hello I'm interested in fabricating a microbolometer electromagnetic radiation detector. Extensive research shows that vanadium oxide is one of the best materials to use for such a device. I'm interested if anyone has information on the deposition and patterning of Vanadium Oxide. Any advice much appreciated. Many thanks, Dr. James Paul Grant
