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…
Intrinsic and extrinsic corrugation of monolayer graphene deposited on SiO2
V. Geringer, M. Liebmann, T. Echtermeyer +5
Using scanning tunneling microscopy (STM) in ultra high vacuum and atomic force microscopy, we investigate the corrugation of graphene flakes deposited by exfoliation on a Si/SiO2…
