Atomic Control of Strain in Freestanding Graphene
P. Xu, Y. Yang, S. D. Barber +8
In this study, we describe a new experimental approach based on constant-current scanning tunneling spectroscopy to controllably and reversibly pull freestanding graphene membranes…

A Pathway between Bernal and Rhombohedral Stacked Graphene Layers with Scanning Tunneling Microscopy
P. Xu, Y. Yang, D. Qi +7
Horizontal shifts in the top layer of highly oriented pyrolytic graphite, induced by a scanning tunneling microscope (STM) tip, are presented. Excellent agreement is found between…

Heavy doped ABA stacked trilayer graphene: triple splitting of its Raman G peak
S. S. Lin, B. G. Chen, W. Xiong +4
For the first time, we have observed the obvious triple G peak splitting of ABA stacked trilayer graphene. The G peak splitting can be quantatively understood through the different…
