Apparent rippling with honeycomb symmetry and tunable periodicity observed by scanning tunneling microscopy on suspended graphene
A. Georgi, P. Nemes-Incze, B. Szafranek +4
Suspended graphene is difficult to image by scanning probe microscopy due to the inherent van-der-Waals and dielectric forces exerted by the tip which are not counteracted by a sub…
Diffractive wave guiding of hot electrons by the Au (111) herringbone reconstruction
F. Libisch, V. Geringer, D. Subramaniam +2
The surface potential of the herringbone reconstruction on Au(111) is known to guide surface-state electrons along the potential channels. Surprisingly, we find by scanning tunneli…
Wave function mapping in graphene quantum dots with soft confinement
D. Subramaniam, F. Libisch, Y. Li +11
Using low-temperature scanning tunneling spectroscopy, we map the local density of states (LDOS) of graphene quantum dots supported on Ir(111). Due to a band gap in the projected I…
Electrical transport and low-temperature scanning tunneling microscopy of microsoldered graphene
V. Geringer, D. Subramaniam, A. K. Michel +7
Using the recently developed technique of microsoldering, we perform a systematic transport study of the influence of PMMA on graphene flakes revealing a doping effect of up to 3.8…
Bistability and oscillatory motion of natural nano-membranes appearing within monolayer graphene on silicon dioxide
T. Mashoff, M. Pratzer, V. Geringer +4
The recently found material graphene is a truly two-dimensional crystal and exhibits, in addition, an extreme mechanical strength. This in combination with the high electron mobili…
