**5. Conclusions**

In conclusion this article shows vanadium oxide as a versatile material that can be used in multiple applications. VO2 has the potential to be a suitable candidate for smart applications, thanks essentially to its SMT behavior. Functionality of conventional Metasurfaces can be improved multifold by incorporating a VO2 sublayer in the device. The variety and ease at which VO2 layers can be integrated to metamaterial makes it an ideal candidate for future optoelectronic devices and smart responsive metasurfaces.

Looking further deep into the mechanism of the SMT in VO2 reveals an interesting facet of these films. The narrow hysteretic region near phase transition, comprising electrically and optically contrasting media, makes VO2 by itself a promising metasurface. This naturally occurring disordered state can be controlled with accurate temperature inputs and the ratio of the semiconducting to metallic parts can be configured spatially over the whole surface or selectively on a part of the metasurface. The rich physics involved in this phenomenon will help to further understand the mechanisms of phase transitions in the fundamental point of view whereas, the unique properties displayed by the material will inspire application possibilities new generation of semiconducting devices.
