傳統的二維材料轉印中分為濕式轉印以及乾式轉印,濕式轉印一般都會使用甲基丙烯酸甲酯(Polymethylemthacrylate;PMMA)作為轉印媒介,但此方式往往困擾於去除PMMA光阻聚合物時,光阻殘留液體影響到二維材料的電性以及鍵結等特性。而傳統乾式轉印法所使用的膠帶以及其聚合物也往往汙染樣品,且無法轉印置所需的區域。本文改以聚二甲基矽氧烷(Polydimethylsiloxane,PDMS)作為剝離與轉印二維材料的媒介,提供了全程從剝離與轉印,完全乾式的轉印形式。本文運用此技術應用於轉印石墨烯、拓樸絕緣體(Bi_2 Se_3)以及二硫化鉬(MoS_2)製作成場效電晶體元件,且製備石墨烯霍爾元件以及以氮化硼為基底的石墨烯場效電晶體,並以拉曼光譜檢驗樣品經轉印後仍保持與轉印前良好與相同的品質,並量測到Shubnikov-de Hass effect。
