This Doctoral Enhancement Program will provide support for a PhD graduate student in condensed matter/materials physics. The program will fund a series of collaborative scientific experiments with two Italian scientists at the NANOSPECTROSCOPY Beamline of the ELETTRA synchrotron facility in Trieste, Italy. The experiments will involve spectromicroscopy measurements on exfoliated mono- and multilayer graphene, with the goal of understanding the nature of the graphene surface morphology, including its intrinsic thermodynamic stability and extrinsically induced surface corrugation. The experiments will examine the temperature dependence of the surface corrugation as well as its behavior under bias, and changes in other extrinsic variables. From the point of view of education, this Doctoral Dissertation Enhancement Program (DDEP) has the specific goal of broadening the scientific research horizons of a PhD student. The proposed experiments at ELETTRA are particularly useful in this regard as they 1) involve a research experience at a state-of-the-art third generation synchrotron with unique beamlines and 2) involve interactions with multiple international scientists and fellow students from Italy and other European countries.

该博士生强化计划将为凝聚态物质/材料物理学的博士研究生提供支持。该计划将资助与两名意大利科学家在意大利的里雅斯特的Elettra同步加速器设施的纳米光谱光束线上进行的一系列合作科学实验。这些实验将包括对剥离的单层和多层石墨烯进行光谱显微镜测量，目的是了解石墨烯表面形态的性质，包括其内在的热力学稳定性和外部诱导的表面波纹。这些实验将考察表面波纹的温度依赖性，以及它在偏压下的行为，以及其他外部变量的变化。从教育的角度来看，这个博士论文增强计划(DDEP)的具体目标是开阔博士生的科研视野。Elettra拟议的实验在这方面特别有用，因为它们1)涉及在具有独特光束线的最先进的第三代同步加速器上的研究经验，2)涉及与多名国际科学家和来自意大利和其他欧洲国家的同学的互动。
