地点:强磁场5楼报告厅 

报告题目:Gate-controlled Two-dimensional materials

报告人:张远波(复旦大学)

报告摘要:

Two-dimensional (2D) atomic crystals, best exemplified by graphene, have emerged as a new class of material that may impact future science and technology. Our group at Fudan University has been actively exploring new 2D materials with peculiar electronic properties. In this talk I will discuss two 2D materials that we found particularly interesting – black phosphorus and 1T-TaS2. These two layered materials have vastly different properties. Black phosphorus is a 2D semiconductor, and its superior material quality has recently enabled us to observe the integer quantum Hall effect. 1T-TaS2, on the other hand, is a metal with a rich set of charge density wave phases. We explore their electronic properties while the doping and dimensionality of the 2D systems are modulated.     

报告人简介:张远波教授于2006年获得纽约哥伦比亚大学物理系博士学位,之后获加州大学伯克利分校Miller Fellowship,从事博士后研究,2009年被聘为复旦大学特聘教授,从2011年至今,为复旦大学物理系教授、博士生导师,2013年获得“求是杰出青年学者奖”。张远波教授立足学科前沿,之前的工作主要集中在石墨烯的制备,电学输运特性,扫描隧道能谱,以及远红外能谱的测量。他与合作者的工作(以及英国的Geim实验组的工作)引领了全球对石墨烯的研究。他一直活跃在这个领域的前沿,以实验凝聚态物理为研究方向,发展新的样品制备和探测手段来研究其它低维度系统的结构和电学性质,在极端物理条件下(极低温度,超强磁场)用电子输运的办法来观察所有这些低维电子体系的电学特性等方面做出了杰出的贡献,在Nature, Nature Nanotechnology, Nature Physics, Phys. Rev. Lett等国际顶级期刊上发表多篇科研论文。
