  • Abstract
    Measurement results on phase changes of SAW passing through a waveguide structure fabricated on LiNbO3 plate by lithography with photoresist patterning by E-beam without any photomask are presented. Discontinuities and hysteresis in the phase versus temperature dependence in nitrogen atmosphere as well as large SAW phase changes (⩾ 180 degrees) as vapors of water containing analyte adsorption on the sample surface have been observed. Qualitative explanation of the results based on the reconstruction of the ferroelectric microdomain structure in E-beam damaged LiNbO3 as temperature changes and with the formation of a thin film of water on the sample surface is suggested
