Simulation and preparation of hybrid one dimensional photonic crystal containing phase transition vanadium dioxide
Source abstract
Abstract
Abstract Reflectance curve and internal power distribution of one-dimensional photonic crystal constructed with germanium (Ge) and zinc sulfide (ZnS) were calculated and analyzed. Phase transition vanadium dioxide (VO2) was then introduced into this multilayer, and the average reflectance of the hybrid structure between 3 and 5 μm reaches 89.15%, and then decreases to 66.45% after VO2 transferred to the metallic phase. The introduction of VO2 bring a clear boundary in the power distribution inside the structure. physical vapor deposition (PVD) and spin-coating method (SCM) were applied in the deposition of this multilayer. Testing results like microscopic scanning electron microscopy (SEM) show a high accordance with that of design. X-ray diffraction (XRD) technology was also applied and confirmed the existence of monoclinic VO2. The phase transition induced thermal effect was studied by analyzing radiant temperatures and hemispherical band emissivity.
