High-quality ZnO thin films on c-plane sapphire (Al2O 3) substrates were prepared by plasma-molecular beam epitaxy (P-MBE). The influence of growth temperature on growth mode of ZnO was investigated. Real-time monitored by reflection high-energy electron diffraction (RHEED) images show that  below 500 C  ZnO thin film was grown by three-dimension (3D) growth mode. While the two-dimension (2D) growth mode was obtained above growth temperature of 650 C. Atomic force microscopy (AFM) images present that the surface morphology of ZnO thin film with 2D growth is improved and X-ray rocking curves (XRC) indicate that the full width at half maximum (FWHM) of the ZnO (0 0 2) peak becomes narrow. From the photoluminescence (PL) spectra  ultraviolet (UV) emission peak exhibits obvious blue-shift for the samples grown at lower temperature  which is attributed to the effect of the quantum confinement arisen from small crystal grain sizes. The minimum carrier concentration of N=7.661016 cm-3 was obtained in the ZnO thin films with the 2D grown  which is closed to that of bulk ZnO. 2005 Elsevier B.V. All rights reserved.

The MOEMS 22 optical switch with slant lower electrode and with torsion beam on silicon is designed and analyzed theoretically. Analytical formulae for the squeeze film damping coefficient and the squeeze film damping moment on the cantilever beam of the optical switch are derived. Based on the torsion dynamics theory  the technique and relative results are presented for analyzing the actuating voltage and the switch time. The optimized result of parameters is as: length  width and thickness of the torsion beam are 700  12 and 10 m  length and width of the cantilever beam are 1900 and 1000 m  length and width of the balance beam are 100 and 1000 m  shortest spacing between the upper and lower electrodes is 0.05 m  and highness of the lower electrode is 55 m  respectively. The actuating voltage is less than 10 V  and the switching time of Ton and Toff are 1.30ms and 1.25ms  respectively. The computed results show that the air squeeze film damping is an important factor for the study of dynamic response on MOEMS optical switch.
