摘要

有機場效電晶體元件近幾年來相當的被受矚目，因為其具有可撓性、重量輕、可以利用溶液製程以及低成本，而若要使有機場效電晶體元件有良好的效能表現，介電層的選擇固然是很重要的因素，先前的研究多以無機或合成有機材料做為介電層材料,但往往會製造出大量的電子廢棄物。因此本研究選擇天然的生物蛋白質膠原蛋白做為介電材料，膠原蛋白具有生物相容性、生物可吸收性、生物可降解性、無毒性…等優點。
本實驗分為兩個部分，第一部分是在膠原蛋白中另外添加了介面活性劑CTMA(Hexadecyltrimethylammonium chloride)做為介電層，來改善膠原蛋白對水的敏感性,降低膠原蛋白薄膜之親水能力，進而提升電性效能，由實驗結果可證明，當添加3.0 wt% CTMA於膠原蛋白中，其元件的電洞遷移率(mobility)可達到3.36×10-2 cm2V-1s-1且電流開關比(on/off ratio)可達到2.7×106，電性表現有顯著的提升。另一個更引人注目的是先前沒有人使用膠原蛋白製備出電晶體式記憶體，第二部分本研究將導電小分子(1-aminopyrene)利用介面活性劑帶入膠原蛋白中製備出場效電晶體式記憶體之實驗，由結果可知隨著小分子的添加量上升，記憶體的性能也跟著提升。由於實驗所屬的材料為生物性材料，將來在生物性感測或生物體醫療材料上都可以有很好的發展。

Organic field-effect transistor devices have gained much attention in recent years attract due to their advantages of flexibility, light weight, solution processibility and low manufacturing cost. The field-effect mobility (μFET) is mainly affected by the organic material in the active layer. The dielectric material is another factor able to influence the mobility value of OFETs. However, some inorganic or organic materials in device are non-environmentally, many electronic litters are generated from inorganic device. Therefore, in this study, we choose natural biological proteins collagen as dielectric material. The advantage of collagen are biocompatible, bioresorbable, biodegradable, and non-toxic.
The experiment was divided into two parts. The first part, cationic surfactant CTMA(Hexadecyltrimethylammonium chloride) were added into collagen and the cationic surfactant CTMA - collagen complexes as gate dielectrics to improve collagen water sensitive and reduce the hydrophilic of collagen, the electrical performance was enhanced. From the experimental results proved that the 3.0wt%-CTMA show an average mobility of 3.36×10-2 cm2V-1s-1 and on/off ratio can reach 2.7×106. Another even more striking is that previously no one used collagen to fabricate transistor type memory. The second part, non-water soluble 1-aminopyrene to be gate electret via CTMA brought into collagen water solution. Collagen-CTMA-1-aminopyrene composite films were used to fabricate OFETs type memory device. From the results, the ranges of bias hysteresis were proportional to contents of 1-aminopyrene means memory performance upgrade also followed content of 1-aminopyrene. Since the collagen belongs biological material. The device in bio-medical sensing or organisms of medical materials can have a very good development in the future.
