  • This paper describes the deposition and characteristics of electrochromic tungsten oxide thin films for electrochromic smart windows. Tungsten Oxide thin films(WO$_3$) are deposited by thermal evaporation techniques. By varying deposition parameters, WO$_3$ thin films exhibit different optical properties. The electrochromic devices are consist of ITO glass/ WO$_3$ thin films/ LiClO$_4$-propylene carbonate electrolyte/ counter electrode. The electrochromic properties of tungsten oxide thin films with different deposition condition ale investigated.

  • Si thin films on p-type (100) Si substrate have been fabricated by pulsed laser deposition technique using a Nd:YAG laser. The pressure of the environmental gas during deposition was varied from 1 to 3 Torr. After deposition, Si thin film has been annealed again at nitrogen ambient. Strong violet-indigo photoluminescence have been observed from Si thin film annealed in nitrogen ambient gas. As increasing environmental gas pressure, weak green and red emissions from annealed Si thin films also observed by photoluminescence.

  • The highly c-axis oriented zinc oxide thin films were deposited on Sapphire(0001) substrates by reactive RF magnetron sputtering. The characteristics of zinc oxide thin films on RF power, substrate-target distance, and substrate temperature were investigated by XRD, SEM and EDX analyses. The physical characteristics of zinc oxide thin films changed with various deposition conditions. The higher substrate temperatures were, The better crystallinity of zinc oxide thin films. The highly c-axis oriented zinc oxide thin films were obtained at sputter pressure 5mTorr, rf power 200W, substrate temperature 350.deg. C, substrate-target distance 5.5cm. In these conditions, the resistivity of zinc oxide thin films deposited on pt/sapphire was 12.196*10$^{9}$ [.ohm.cm].

  • Piezoelectric thin film such as ZnO and AlN can be applicable to FBAR (Film Bulk Acoustic Resonator) device of thin film type and FBAR can be applicable to MMIC. The characteristic of FBAR device is variable according to the deposition conditions of piezoelectric thin film when preparation of thin film by sputtering method. In this study, we prepared ZnO thin film for FBAR using Facing Targets Sputtering apparatus which can be deposited fine Quality thin film because temperature increase of substrate due to the bombardment of high-energy particles can be restrained. And crystalline and c-axis preferred orientation of ZnO thin film with deposition conditions was investigated by XRD.

  • IGZO transparent conductive thin films were widely used as transparent electrode of optoelectronic devices. We have studied the optical and electrical properties of IGZO thin films. The IGZO thin films were deposited on the corning 1737 glass by RF magnetron sputtering method. The RF power in sputtering process was varied as 25, 50, 75and 100 W, respectively. All of the thin films transmittance in the visible range was above 85%. XRD analysis showed that amorphous structure of the thin films without any peak. The thin films were electrically characterized by high mobility above $13.4cm^2/V{\cdot}s$, $7.0{\times}10^{19}cm^{-3}$ high carrier concentration and $6{\times}10^{-3}{\Omega}-cm$ low resistivity. By the studies we found that IGZO transparent thin film can be used as transparent electrodes in electronic devices.
