Summary:	本篇論文以奈米碳管在照光實驗下,其照光能帶與強度變化做為討論。在照光實驗中,因高強度的光源照射後,在光電效應下會使得載子被激發,而提高導電性。在特定波長光照射下,觀察其電性變化,使用阻抗分析儀進行量測,發現其奈米碳管在低頻區域產生阻抗不穩定,使其等效電子電洞對造成等效電容改變,進一步使用低頻雜訊參數量測系統進行量測,其測量結果奈米碳管在照光狀態下與未照光相比較,照光狀態下的奈米碳管其阻抗產生改變,有一可能為碳管成為光學天線的角色,加強了光子的吸收和電子的發射。過去有許多文獻討論碳管在外加電場下的電子場發射特性,然而碳管因照光而產生的光電子發射卻很少被注意,顯而易見,奈米碳管吸收光而產生光電子的效應會對許多應用產生極其影響。 This thesis discusses the photoelectric effect under irradiation different spectrum using discontinuous Carbon nanotubes(CNTs), the carriers are excited after high intensity irradiation, which appears resistance reduction. Some specific wave length irradiation was found electrical properties variation under impedance analyzer measurement. The discontinuous carbon nanotubes produced unstable impedance in low frequency region, probably because of carrier tunneling, which can be explained by capacitance shift from equivalent circuit modeling. Low frequency noise measurement indicates that impedance change under the illumination. CNTs can be the role of the optical antenna, because they enhanced photon absorption and electron emission.
