Summary: | One dimensional photonic crystal structure with a vanadium dioxide (VO2) layer sandwiched by germanium (Ge) and zinc sulfide (ZnS) layers was deposited using physical vapor deposition (PVD) combined with spin-coating method (SCM). Microstructure of this multilayer is characterized with scanning electron microscopy (SEM) and X-ray diffraction (XRD). The result shows a high accordance with design. The phase transition of VO2 induced mid-infrared modulation was studied by analyzing the measured radiant temperatures and hemispherical total emissivity. The trend of those two data varies with different thickness of VO2, which provides guidance to decide the thickness of VO2 at certain circumstance.
•This paper seeks to realize 1D photonic crystal that containing semiconductor-to-metal transition VO2 using physical vapor deposition (PVD) combined with spin-coating method (SCM). The combination of those two deposition methods is novel for the multilayer structure.•The radiant temperatures and hemispherical total emissivity and their trend reveal that temperature will put on impact on the infrared radiation of this structure, so it is promising to realize temperature-dependent infrared emitter based on this 1D photonic crystal.•The semiconductor-to-metal transition VO2 based 1D PC with mid-infrared modulation is rarely studied before. |
