本研究提出以陽極氧化鋁膜(Anodic Alumina Oxide, AAO)為基材,在陽極氧化鋁膜板背面以微影蝕刻製作寬為500m、長度1.2 cm之微流道,再於微流道中沉積單壁奈米碳管(SWNTs),接著於基板上相對於微流道之另一面濺鍍一層金薄膜為閘極,然後在奈米碳管上澆注一層高分子聚二甲基矽氧烷(PDMS)當作保護層,隔絕SWNT與外界環境之接觸,接著在PDMS上濺鍍一層氧化銦錫(ITO)薄膜做為閘極之對電極,產生類金氧場效電晶體(MOSFET)效應,開發新型紅外線感測器,而感測元件之電阻可藉由微流道之尺寸以及奈米碳管之沈積量精確控制。光電流量測結果驗證本研究所提之紅外線感測器確實可有效在常溫常壓、低光源強度(17 W/cm2)以及低外加電壓(VDS = 0.01V) 下感測紅外光,在-0.2V閘極偏壓下感測元件之開關紅外線電導變化為2.11 %,其光反應時間可達0.5sec。

In this research, a metal oxide semiconductor field effect transistor (MOSFET) like infrared (IR) sensing method is presented. The orderly uneven barrier-layer surface of an anodic aluminum oxide (AAO) membrane was used as a substrate. The thickness of the barrier-layer was reduced by phosphoric acid etching. Following, a microchannel was transferred to the barrier-layer by photolithographic process. Single wall carbon nanotubes (SWNTs) were deposited into the microchannel as sensing element. A gold thin film that served as the gate electrode was sputtered on the opposite side of the barrier-layer of the AAO substrate. A thin layer of polydimethylsiloxane (PDMS) was then casted on the SWNTs to insulate the SWNTs from the surrounding ambiance. A thin film of indium tin oxide (ITO) was sputtered on the PDMS layer as the counter electrode of the gate electrode. The conductance of the sensing element could be precisely controlled by the width of the microchannel and the amount of the deposited SWNTs. Experiments demonstrated that the proposed MOSFET like IR sensor could effectively sense IR signal in the air at room temperature under a very weak power intensity (17 W/cm2) of IR illumination and an 0.01 V applied drain-source voltage. A 0.5 sec photocurrent response and a 2.11 % of conductivity increasing of the sensing element were measured, respectively.
