解釋
表面膜勢-
Zno film is a novel - direct compound semiconductor with wide band gap energy of 3. 37ev and a exciton binding energy 60mev at room temperature. due to its the prerequisite for visible or ultraviolet light emission at room temperature, it has the tremendous potential applications for ultraviolet detectors, leds, lds. zno thin film is used widely and effectively in the fields of surface acoustic wave devices, solar cell, gas sensors, varistors and so on because of its excellent piezoelectrical performance
室溫下禁帶寬度為3 . 37ev ，激子束縛能為60mev ，具備了室溫下發射紫外光的必要條件，在紫外探測器、 led 、 ld等領域有著巨大的發展潛力； zno薄膜以其優良的壓電性能、透明導電性能等使其在太陽能電池、壓電器件、表面聲波器件、氣敏元件等諸多領域得到廣泛應用。 -
To achieve accurate detection of surface potential, the measurement of the contact potential difference of the zno / si step was also carried out. polarization - related surface properties of ferroelectric thin films were investigated by kelvin probe force microscopy ( kpfm ), leading to the discovery of asymmetric charge writing on the surface of pb ( zr _ ( 0. 55 ) ti _ ( 0. 45 ) ) o _ 3 ( pzt ) thin film
為了優化儀器的檢測靈敏度和穩定性，選用氧化鋅薄膜上的zno / si臺階作為測試對象，檢測了zno / si的接觸電勢差;通過改變儀器系統參數，發現針尖-樣品距離和掃描速度對接觸電勢差的檢測結果影響顯著。 -
Otherwise, using the ta buffer layer can effectively reduce the surface roughness. in addition, measured by our measurement system, the polycrystalline the film has similar negative magnetoresistance effect to single - crystalline film, so it is potential to be applied in spintronic devices
通過磁電子輸運測試系統研究制備的薄膜還發現多晶fe _ 3o _ 4具有同單晶fe _ 3o _ 4類似的負磁電阻特性，因此有望將多晶fe _ 3o _ 4薄膜應用到自旋電子器件中。 -
The high quality laser provides higher intensity / surface ratio with less overall laser power and in this way avoids the potential danger of heating up the thin film or the substrate
高品質的激光器可以在較小的總功率提高光強和面積的比率，從而避免使薄膜或基底過熱。
