石墨烯具有獨特的電學,熱力學及機械性能,在科學研究和技術領域受到廣泛的關注。特別是,以石墨烯為基礎的石墨烯場效應電晶體近年來得到了快速發展,使其成為後矽基時代的可選用材料之一。不同于傳統的體半導體材料,石墨烯具有獨特的二維結構;它與周圍環境的介面相互作用對石墨烯器件有決定性的影響。研究石墨烯的介面特性在石墨烯應用中具有重要的意義。因此研究者對於發掘在納米尺度上的石墨烯介面規律及由此獨特的介面特性所導致的電子結構、載流子輸運性質和其他相關現象具有濃厚的興趣。在本論文中,我們從實驗和理論兩個方面對石墨烯與不同基底的介面耦合機制,由金屬電極到石墨烯的電荷注入以及其表面的吸附物對石墨烯的摻雜作用進行了深入细致的研究。<br>首先,通過對薄層石墨烯的表面功能化,可以對其電子結構進行有效的控制和調整。在石墨烯薄片表面吸附不同的自組裝有機分子,可以實現對石墨烯的電子和空穴摻雜。另外,我們對由電子束放射產生的摻雜效應也進行了研究。我們發現當利用電子束處理包含不同層數的石墨烯薄片時,可以形成石墨烯pn結。 其次,我們對石墨烯基底對於石墨烯的重要作用進行了深入的探究。由於商用矽片中存在的帶電雜質及石墨烯褶皺對放置於其上的石墨烯樣品產生了極大的影響,使得石墨烯的遷移率遠小於其理論值。為消弱由基底產生的不利影響,我們利用自組裝單分子膜對二氧化矽/矽襯底的表面進行鈍化處理,從而減少不必要的散射。通過鈍化處

Inkjet printing of functional materials with specific electrical, optical, chemical, biological or structural functionalties has gained significant interest as an alternative to conventional vacuum deposition and photolithographic patterning, methods, especially in the area of low-cost and karge-area electronics.
