The glass and crystalline glass-solders of Li2O-ZnO-SiO2 system were prepared by conventional melt technology. The various factors effecting on glass ceramics and glass were investigated,which include glass chemical composition and heat-treatment and so on. And then by means of XRD, DTA, IR and SEM, the structure and properties of the glass and glass-ceramic were studied. The coefficient of linear expansion , transform temperature and soft temperature wer measured. And then the factors that effect the mechanical strength of glass-ceramic were discussed and the fluxion property was determined and the crystallization course and mechanism were discussed, which can provide certain therial reference value for practice producing and glass seals to glass, ceramics and metal.

EDS and Surface-profile results indicate that the stoichiometries of all the samples approach 2:3 and the thicknesses are over 500nm. XRD results indicate that the major diffraction peaks of the film match those of Bi2Te3.The film growth exhibits preferred orientation at (015) phase and many Bi, impurity peaks are observed. Hall and Seebeck coefficient measurement reveals that all the samples are n-type with the carrier density of 10^23cm^-3 and conductivity of 10^-5Sm^-1 which confirm the samples have nice thermoelectrically properties.

能谱分析和台阶仪测量结果显示本文所制备的薄膜Bi：Te原子比接近2：3，厚度都大于500nm；XRD测量结果显示薄膜的主要衍射峰与Bi2Te3标准衍射峰相同，在（015）晶面上择优选向明显，有少量的Bi、杂质峰存在；霍尔系数测试及Seebeck系数测量结果显示，薄膜都为n型半导体薄膜，载流子浓度量级为10^23cm^-3，电导率量级10^-5Sm^-1，具有良好的电学性能。
