Abstract:	近年來有學者指出蕭特基接觸奈米感測元件在紫外線、氣體與生物感測上都可以提供很好的感測靈敏度。為了進一步使蕭特基接觸感測元件在訊號輸出強度方面有有效的提升。本研究利用氧化鋅奈米線製成多通道奈米感測元件，藉由通道與蕭特基電極端的增加，使感測時的訊號輸出強度提升。在紫外線感測實驗中，多通道蕭特基接觸元件不僅可以提升光電流輸出訊號，也保留了單通道蕭特基接觸元件在元件操作上良好的穩定度。而在一氧化碳的感測實驗，甚至對5ppm 的氣體也能有很好的訊號辨識度。藉由研究多通道蕭特基接觸元件，更能提升未來感測元件在實際應用可能性。 The Schottky-gate nanosensor has good sensitivities for UV, gas and biomolecule detection. To improve the current output level for commercial application, the multi-channels device was fabricated by using ZnO nanowire. With increasing the schottky-gate number, the sensitivity and current output of the signal were enhanced. For UV sensing, the current output of the Multi-channels devices were increasing and without degenerating the stability compare to the Single-channel device. For gas sensing, 5ppm CO can be detected at 275℃. The Schottky-gate nanosensor have great applications for gas and UV detection by increasing the Schottky-gate number.
