Chemical vapor deposition growth of bilayer graphene in between molybdenum disulfide sheets
Wojciech Kwiecinski, Kai Sotthewes, Bene Poelsema +2
Direct growth of flat micrometer-sized bilayer graphene islands in between molybdenum disulfide sheets is achieved by chemical vapor deposition of ethylene at about 800 °C. The tem…
Structural and electronic properties of germanene on MoS
L. Zhang, P. Bampoulis, A. N. Rudenko +5
To date, germanene has only been synthesized on metallic substrates. A metallic substrate is usually detrimental for the two-dimensional Dirac nature of germanene because the impor…
Alloying, de-alloying and reentrant alloying in (sub-)monolayer growth of Ag on Pt(111)
Maciej Jankowski, Esther van Vroonhoven, Herbert Wormeester +2
An in-situ nanoscopic investigation of the prototypical surface alloying system Ag/Pt(111) is reported. The morphology and the structure of the ultrathin Ag-Pt film is studied usin…
Latent heat induced rotation limited aggregation in 2D ice nanocrystals
Pantelis Bampoulis, Martin H. Siekman, E. Stefan Kooij +3
The basic science responsible for the fascinating shapes of ice crystals and snowflakes is still not understood. Insufficient knowledge of the interaction potentials and the lack o…
Visualization of steps and surface reconstructions in Helium Ion Microscopy with atomic precision
Gregor Hlawacek, Maciej Jankowski, Herbert Wormeester +3
Helium Ion Microscopy is known for its surface sensitivity and high lateral resolution. Here, we present results of a Helium Ion Microscopy based investigation of a surface confine…
Helium Ion Microscopy
Gregor Hlawacek, Vasilisa Veligura, Raoul van Gastel +1
Helium Ion Microcopy (HIM) based on Gas Field Ion Sources (GFIS) represents a new ultra high resolution microscopy and nano-fabrication technique. It is an enabling technology that…
The influence of substrate temperature on growth of para-sexiphenyl thin films on Ir{111} supported graphene studied by LEEM
Fawad S. Khokhar, Gregor Hlawacek, Raoul van Gastel +3
The growth of para-sexiphenyl (6P) thin films as a function of substrate temperature on Ir{111} supported graphene flakes has been studied in real-time with Low Energy Electron Mic…
The difference between Si and Ge(001) surfaces in the initial stages of growth
G. Brocks, J. H. Snoeijer, P. J. Kelly +2
The initial stages of growth of Ge and Si on the Ge(001) surface are studied and compared to growth on the Si(001) surface. Metastable rows of diluted ad-dimers exist on both surfa…
