The semiconductor industry and information revolution in the twentieth century were built on the element of silicon. As first postulated by Gordon Moore of Intel, Moore’s Law holds that the number of transistors on a chip will double every two years. We have benefited tremendously from these technology advances, and our lives have been forever changed. With silicon device fabrication approaching its physical limits, the search for the next generation of electronic materials has been one of the major research topics in materials science. In the past few years, a new material named graphene has attracted the attention of researchers in physics, chemistry, and engineering. Graphene, a single atomic layer of carbon atoms arranged in a honeycomb lattice, is a unique two-dimensional system with many interesting physical properties that have been identified and investigated within the framework of “massless relativistic fermions.” The 2010 Nobel Prize in Physics was awarded to Andre Geim and Konstantin Novoselov for their experimental work on graphene. Many scientists believe that graphene can provide a new platform material that would allow the semiconductor industry to continue its progress described by Moore’s Law to produce ever-smaller and faster electronic devices. In this talk, I will explain the physics of graphene and provide a perspective on this fascinating material.
二十世紀的半導體工業和資訊革命是在矽元素上發展出來的。高登摩爾曾歸納出一個摩爾定律描述它的進展:晶片上半導體的數目每兩年就會加倍。這些發展已經大大地改變了我們的生活。但是矽元件的生產方式已經到達了物理極限，因此尋找新興電子材料成為材料科學上的重要課題。在過去幾年中，石墨烯成為眾人矚目的新材料。石墨烯是由單層碳原子形成的特殊二維網狀結構。它具有很多奇妙有趣的物理性質。2010年的物理諾貝爾獎就頒給了Andre Geim和Konstantin Novoselov獎勵他們在這方面的研究。很多人覺得石墨烯將是延續摩爾定律產生更小更快電子元件的關鍵材料。在這個演講中，我將解釋石墨烯的物理性質，以及描述最近的發展和未來的展望。
