High-strain-induced local modification of the electronic properties of VO thin films
Yorick A. Birkhölzer, Kai Sotthewes, Nicolas Gauquelin +8
Vanadium dioxide (VO2) is a popular candidate for electronic and optical switching applications due to its well-known semiconductor-metal transition. Its study is notoriously chall…
Free energy of domain walls and order-disorder transition in a triangular lattice with anisotropic nearest-neighbor interactions
Martina Tsvetanova, Kai Sotthewes, Harold J. W. Zandvliet
We have derived exact expressions for the domain wall free energy along the three high-symmetry directions of a triangular lattice with anisotropic nearest-neighbor interactions. T…
Valley protected one-dimensional states in small-angle twisted bilayer graphene
J. D. Verbakel, Q. Yao, K. Sotthewes +1
Theory predicts that the application of an electric field breaks the inversion symmetry of AB and BA stacked domains in twisted bilayer graphene, resulting in the formation of a tr…
Dual modulation STM: Simultaneous high-resolution mapping of the differential conductivity and local tunnel barrier height demonstrated on Au(111)
V. J. S. Oldenkotte, F. J. Witmans, M. H. Siekman +6
We present a scanning tunneling microscopy (STM) technique to simultaneously measure the topography, the local tunnel barrier height (dI/dz) and the differential conductivity (dI/d…
Thickness-Dependent Band Gap Modification in BaBiO
Rosa Luca Bouwmeester, Alexander Brinkman, Kai Sotthewes
The material BaBiO is known for its insulating character. However, for thin films, in the ultra-thin limit, metallicity is expected because BaBiO is suggested to return…
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…
