Technical:The goal of this Faculty Early Career Development (CAREER) project at the Pennsylvania State University is to explore mesoscopic physics in a newly discovered two-dimensional material: graphene. Graphene, a single sheet of carbon atoms arranged in a hexagonal lattice, possesses a set of unusual physical properties which may lead to new physics in two dimensions. A closely-coupled second layer (bilayer graphene) enhances the richness and complexity of the system, providing even more intriguing opportunities. Graphene is also a promising material for high-speed electronics thanks to its highly mobile charge carriers. The uniting theme of this project is to use geometrical, electrical and chemical manipulations of various substrates and adsorbates to modulate and study the electronic properties of single and bilayer graphene. Mesoscopic confinement structures will be created to explore new phenomena arising from graphene's unique band structure, lattice symmetry and spin interactions. The educational component of this project will provide career training for graduate and undergraduate researchers. Research results from the PI's lab and the field of nanoscience will be disseminated to the public through on- and off-campus venues including local libraries and the arts festival. The PI will use her role as a co-coordinator of the Penn State REU program to draw the participation of students from underrepresented groups in this project.Non-technical:The goal of this Faculty Early Career Development (CAREER) project at the Pennsylvania State University is to explore the electronic properties of a newly discovered two-dimensional material: graphene.

技术：宾夕法尼亚州立大学的教师早期职业发展（Career）项目的目标是探索一种新发现的二维材料：石墨烯的介观物理学。石墨烯是一种排列成六角形晶格的单片碳原子，它具有一系列不同寻常的物理性质，可能会导致二维物理学的新发展。紧密耦合的第二层（双层石墨烯）增强了系统的丰富性和复杂性，提供了更有趣的机会。由于石墨烯具有高度移动的电荷载体，它也是一种很有前途的高速电子材料。该项目的统一主题是使用各种衬底和吸附剂的几何，电气和化学操作来调节和研究单层和双层石墨烯的电子特性。将创建介观约束结构，以探索石墨烯独特的能带结构、晶格对称性和自旋相互作用所产生的新现象。该项目的教育部分将为研究生和本科生研究人员提供职业培训。PI实验室和纳米科学领域的研究成果将通过包括当地图书馆和艺术节在内的校内和校外场所向公众传播。PI将利用她作为宾夕法尼亚州立大学REU项目的联合协调员的角色，吸引来自代表性不足群体的学生参与该项目。非技术：宾夕法尼亚州立大学的教师早期职业发展（Career）项目的目标是探索新发现的二维材料石墨烯的电子特性。石墨烯是一种排列成六角形晶格的单片碳原子，它具有一系列不同寻常的物理性质，可能会导致二维物理学的新发展。紧密耦合的第二层（双层石墨烯）增强了系统的丰富性和复杂性，提供了更多有趣的机会。石墨烯还因其高度移动的电荷载体而成为高速电子产品的一种有前途的新材料。该项目的共同主题是通过石墨烯的几何、电学和化学操作，在微纳米尺度上创造出新颖的结构，并探索其电输运特性。将开发新的设备配置，以利用石墨烯优异的电性能。该项目的教育部分将为研究生和本科生研究人员提供职业培训。PI实验室和纳米科学领域的研究成果将通过包括当地图书馆和艺术节在内的校内和校外场所向公众传播。PI将利用她作为宾夕法尼亚州立大学REU项目的联合协调员的角色，吸引来自代表性不足群体的学生参与该项目。
