Lithography-free Fabrication of High Quality Substrate-supported and Freestanding Graphene devices
W. Bao, G. Liu, Z. Zhao +5
We present a lithography-free technique for fabrication of clean, high quality graphene devices. This technique is based on evaporation through hard Si shadow masks, and eliminates…
Mapping the Dirac point in gated bilayer graphene
A. Deshpande, W. Bao, Z. Zhao +2
We have performed low temperature scanning tunneling spectroscopy measurements on exfoliated bilayer graphene on SiO2. By varying the back gate voltage we observed a linear shift o…
Spatially resolved spectroscopy of monolayer graphene on SiO2
A. Deshpande, W. Bao, F. Miao +2
We have carried out scanning tunneling spectroscopy measurements on exfoliated monolayer graphene on SiO to probe the correlation between its electronic and structural properti…
Atom-by-atom extraction using scanning tunneling microscope tip-cluster interaction
A. Deshpande, H. Yildirim, A. Kara +4
We investigate atomistic details of a single atom extraction process realized by using scanning tunneling microscope (STM) tip-cluster interaction on a Ag(111) surface at 6 K. Sing…
Single atom extraction by scanning tunneling microscope tip-crash and nanoscale surface engineering
Saw Wai Hla, Kai-Felix Braun, Violeta Iancu +1
We report a novel atom extraction mechanism from the native substrate by means of a scanning tunneling microscope tip-crash on a Ag(111) surface at 5 K. Individual atoms are scatte…
