Electronic transition from graphite to graphene via controlled movement of the top layer with scanning tunneling microscopy
P. Xu, Y. Yang, D. Qi +5
A series of measurements using a technique called electrostatic-manipulation scanning tunneling microscopy (EM-STM) were performed on a highly-oriented pyrolytic graphite surface.…
New Scanning Tunneling Microscopy Technique Enables Systematic Study of the Unique Electronic Transition from Graphite to Graphene
P. Xu, Y. Yang, S. D. Barber +5
A series of measurements using a novel technique called electrostatic-manipulation scanning tunneling microscopy were performed on a highly-oriented pyrolytic graphite (HOPG) surfa…
Graphene Manipulation on 4H-SiC(0001) Using Scanning Tunneling Microscopy
P. Xu, M. L. Ackerman, S. D. Barber +8
Atomic-scale topography of epitaxial multilayer graphene grown on 4H-SiC(0001) was investigated using scanning tunneling microscopy (STM). Bunched nano-ridges ten times smaller tha…
Atomic-Scale Movement Induced in Nano-Ridges by Scanning Tunneling Microscopy on Epitaxial Graphene Grown on 4H-SiC(0001)
P. Xu, S. D. Barber, J. K. Schoelz +8
Nanoscale ridges in epitaxial multilayer graphene grown on the silicon face of 4 degree off-cut 4H-SiC (0001) were found using scanning tunneling microscopy (STM). These nano-ridge…
Role of bias voltage and tunneling current in the perpendicular displacements of freestanding graphene via scanning tunneling microscopy
P. Xu, S. D. Barber, M. L. Ackerman +2
Systematic displacement measurements of freestanding graphene as a function of applied bias voltage and tunneling current setpoint using scanning tunneling microscopy (STM) are pre…
Etch-stop method for reliably fabricating sharp yet mechanically stable scanning tunneling microscope tips
G. Basnet, J. K. Schoelz, P. Xu +3
An extension of the direct-current, double-lamella drop-off technique for electrochemically etching tungsten scanning-tunneling-microscope tips is presented. The key fabrication st…
