“…Vanadium sesquioxide ( ) is a transition metal oxide which, like several other such oxides, exhibits a structural phase transition with temperature 1 . In bulk form undergoes the transition at around 155 K where its crystallographic structure changes from a rhombohedral phase at high temperatures to a low temperature monoclinic phase.…”

We present a study of $$\hbox {V}_{2}\hbox {O}_{3}$$ V 2 O 3 thin films grown on c-plane $$\hbox {Al}_{2}\hbox {O}_{3}$$ Al 2 O 3 substrates by reactive dc-magnetron sputtering. Our results reveal three distinct types of films displaying different metal–insulator transitions dependent on the growth conditions. We observe a clear temperature window, spanning 200 $$^{\circ }$$ ∘ C, where highly epitaxial films of $$\hbox {V}_{2}\hbox {O}_{3}$$ V 2 O 3 can be obtained wherein the transition can be tuned by controlling the amount of interstitial oxygen in the films through the deposition conditions. Although small structural variations are observed within this window, large differences are observed in the electrical properties of the films with strong differences in the magnitude and temperature of the metal–insulator transition which we attribute to small changes in the stoichiometry and local strain in the films. Altering the sputtering power we are able to tune the characteristics of the metal–insulator transition suppressing and shifting the transition to lower temperatures as the power is reduced. Combined results for all the films fabricated for the study show a preferential increase in the a lattice parameter and reduction in the c lattice parameter with reduced deposition temperature with the film deviating from a constant volume unit cell to a higher volume.

“…Vanadium can be dissolved in nitric and sulfuric acids but is insoluble in hydrochloric acid . In nature, vanadium is difficult to exist in metal form because it easily reacts with oxygen, even nitrogen and carbon at elevated temperatures. , Vanadium is an important component of specific steel alloys, which provides additional tensile strength and extra protection against rust and corrosion of these materials.…”

In this contribution, we demonstrate room temperature growth of highly oriented single phase nanocrystalline films of VO 2 (A) on glass substrates using pulsed laser deposition (PLD) technique under high oxygen pressure and small target-substrate separation. The structural, morphological, optical, electrical and compositional properties of the deposited thin films have been studied by means of X-ray diffraction, atomic force microscopy, spectrophotometry, 04 probe method and X-ray photoelectron spectroscopy, respectively. The plasma under which VO 2 (A) was grown has been analyzed by means of time-and spaceresolved optical emission spectroscopy (OES) and Langmuir probe (LP) techniques. We evidenced a correlation between growth conditions and plasma characteristics. While OES showed that at the deposition distance corresponding to the length of the visible plasma, the plasma species are completely thermalized and characterized by a very low degree of excitation, LP technique indicated a formation of charged clusters within the gas phase. By combining OES and LP data, a quadruple plasma structure has been shown. The growth of under-stoichiometric (comparing to the parent V 2 O 5 target) nanocrystalline VO 2 (A) phase has been attributed to nanoparticles formation in the gas phase under a plasma environment rarefied in oxygen atoms due to the scattering and backscattering effects. This finding opens 2 up the opportunity to grow VO 2 polymorphs at very low temperature by PLD for novel promising new device functionalities.
