Description
Summary:碩士 === 國立臺南大學 === 電機工程學系碩士班 === 100 === In this study, ZnO:Sb was successfully synthesized, the structure of which was analyzed by SEM, EDX, XRD and PL. It was determined that the synthesized ZnO:Sb NWs’ length is about 10 um, while the Sb atomic doping concentration is 4.27 %, with the PL and XRD images showing that the material has an obvious peak from being affected by Sb. Further, by TEM, we can see that the lattice space is 2.5 Å for the internal structure. The p-type feature was obtained by the Hall, FE and gas sensors. The Hall concentration is +2.88×1012 / cm3, while the FE has a larger work function (6.24 eV) than ZnO (5.4 eV). Then the possible model of the gas sensor phenomenon in the different temperatures is proposed. An acceptable PD response was generated/obtained/created/received (ΔI = 11 μA). In a later section, an exploration of how the different substrate affects the ZnO piezoelectric effect is offered. In this glass and PET were chosen as the substrates, of which PET has a better piezoelectric conversion efficiency than glass. The primary reason for this is because PET has one more deformation space (up and down) than does glass.
