　　講座地點：科學館101

　　摘要：When one writes by a pencil, thin flakes of graphite are left on a surface. Some of them are only one atom thick and can be viewed as individual atomic planes cleaved away from the bulk. Such one atom thick crystals of graphite (dubbed graphene) turned out to be the strongest crystals available to us, the most conductive, most thermally conductive, most elastic, flexible, transparent material, etc, etc, etc. Its electronic properties are particularly exciting: its quasiparticles are governed by the Dirac equation so that charge carriers in graphene mimic relativistic particles with zero rest mass.

　　Still, probably the most important “property” of graphene is that it has opened a floodgate of experiments on many other 2D atomic crystals: BN, NbSe2, TaS2, MoS2, etc. The resulting pool of 2D crystals is huge, and they cover a massive range of properties: from the most insulating to the most conductive, from the strongest to the softest.

　　If 2D materials provide a large range of different properties, sandwich structures made up of 2, 3, 4 … different layers of such materials can offer even greater scope. Since these 2D-based heterostructures can be tailored with atomic precision and individual layers of very different character can be combined together, - the properties of these structures can be tuned to study novel physical phenomena or to fit an enormous range of possible applications, with the functionality of heterostructure stacks is “embedded” in their design.

　　報告人簡介：Prof. KostyaNovoselov graduated from the Moscow Institute of Physics and Technology with a MSc degree in 1997, and was awarded a PhD from the Radboud University of Nijmegen, the Netherlands, in 2004. He became a professor of Physics in the University of Manchester since 2010. He elected the Fellow of the Royal Society since 2011.

　　Professor KostyaNovoselov is an established physicist, specialising in the area of condensed matter physics, mesoscopic physics and nanotechnology. He has broad research interests from mesoscopic phenomena in ferromagnets and superconductors to electronic properties if two-dimensional (2D) electron gas in GaAs/AlGaAsheterostructures and graphene. He also has got a vast background in nanofabrication and nanotechnology. He won a lot of Prize and Awards, among of them, the most important is the Nobel Prize in Physics in 2010 for groundbreaking experiments regarding the two-dimensional material grapheme.
