Stable and reversible phase change performance of TiO2 coated VO2 nano-columns: Experiments and theoretical analysis

Photonic bandgap engineering in (VO2) n /(WSe2) n photonic superlattice for versatile near- and mid-infrared phase transition applications

“…Based on the most recent experimental data and theoretical calculations, the VO 2 MIT is now understood as a cooperative Mott-Peierls transition, including lattice and electron correlation effects [16,23]. The crystallographic phase change from M to R state makes VO 2 attractive for many applications such as infrared memory [24], thermochromic [25][26][27], photoelectric nonvolatile memory [28], gas sensors [29][30][31], smart radiator devices [32], phase change [33], tunable terahertz absorber [34,35] and optoelectronic devices [36]. The tunability range of VO 2 characteristics is crucial for building novel solid-state phase transition devices that can be switched by non-thermal external inputs, in addition to understanding the fundamental physics of strongly correlated behavior of VO 2 underpinning the MIT [37][38][39].…”

Enhanced Thermochromic Performance of VO2 Nanoparticles by Quenching Process

“…Additionally, the transparent matrix covering isolated particles gives rise to higher T lum of the VO 2 nanocomposite coatings. Typically, SiO 2 [23], SnO 2 [24], TiO 2 [25], and Si-Al oxide [26] are common inorganic matrixes for VO 2 nanoparticles. Unfortunately, these matrixes require a strict annealing atmosphere or precisely uniform dispersion of VO 2 in the nanocomposite films.…”
