摘 要：石墨烯是2004年英國科學(xué)家在實(shí)驗(yàn)上首次得到的一種新的碳元素結(jié)構(gòu)形態(tài)，表現(xiàn)出許多非常奇異的性質(zhì)。石墨烯的研究正在成為一個令世人密切關(guān)注的前沿課題，將對整個凝聚態(tài)物質(zhì)科學(xué)的發(fā)展和未來信息器件的研制產(chǎn)生巨大而深遠(yuǎn)的影響。要充分發(fā)揮石墨烯的優(yōu)異性質(zhì)、實(shí)現(xiàn)工業(yè)生產(chǎn)與應(yīng)用、并與現(xiàn)有的硅基技術(shù)完美結(jié)合，必須找到合適的材料制備方法，使得到的石墨烯可以同時滿足3個必要條件：高質(zhì)量、大面積和與硅工藝兼容。目前常用的方法都無法制備出同時滿足這3個條件的石墨烯樣品。該研究為解決這一問題，提出了利用無損硅插層的方法制備高質(zhì)量、大面積、與硅技術(shù)兼容的石墨烯。主要研究內(nèi)容包括4個方面：（1）高質(zhì)量硅插層石墨烯及新型石墨烯類材料的可控制備；（2）硅插層石墨烯的摻雜、修飾與物性調(diào)控；（3）硅插層石墨烯及新型石墨烯類材料的基本物性；（4）研發(fā)基于硅插層石墨烯電子與光電子器件，包括基于該材料的新的器件結(jié)構(gòu)和與硅集成相兼容的技術(shù)。該研究的核心目標(biāo)是：（1）掌握石墨烯材料在金屬單晶表面上的生長機(jī)制，發(fā)展出高質(zhì)量、大面積石墨烯的可控制備方法，掌握硅插層的生長與控制技術(shù)，實(shí)現(xiàn)厚硅可控插層與插層的絕緣化，掌握其他新型石墨烯類材料在金屬表面的生長機(jī)制；（2）掌握硅插層石墨烯的基本物性和調(diào)控方法，理解新型石墨烯類材料的結(jié)構(gòu)對物性的影響；（3）構(gòu)建基于硅插層石墨烯的特殊功能的新型器件。該研究的實(shí)施有望在與硅技術(shù)兼容的硅插層石墨烯材料及新型石墨烯類材料的制備、物性調(diào)控和新型器件探索上取得若干原創(chuàng)性成果，這必將使我國擺脫在石墨烯這一前沿研究領(lǐng)域的落后局面，進(jìn)一步增強(qiáng)我國在納米碳材料研究方面的國際影響力，為我國石墨烯材料和相關(guān)器件的應(yīng)用研究奠定堅(jiān)實(shí)的基礎(chǔ)。
