Realization of a one-dimensional topological insulator in ultrathin germanene nanoribbons
Dennis J. Klaassen, Lumen A. G. Eek, Alexander N. Rudenko +9
Realizing a one-dimensional (1D) topological insulator and identifying the lower dimensional limit of two-dimensional (2D) behavior are crucial steps toward developing high-density…
Moiré-modulated band gap and van Hove singularities in twisted bilayer germanene
Pantelis Bampoulis, Carolien Castenmiller, Dennis J. Klaassen +4
Twisting bilayers of two-dimensional topological insulators has the potential to create unique quantum states of matter. Here, we successfully synthesized a twisted bilayer of germ…
On the mystery of the absence of a spin-orbit gap in scanning tunneling microscopy spectra of germanene
Carolien Castenmiller, Harold J. W. Zandvliet
Germanene, the germanium analogue of graphene, shares many properties with its carbon counterpart. Both materials are two-dimensional materials that host Dirac fermions. There are,…
Spectroscopic signature of surface states and bunching of bulk subbands in topological insulator (BiSb)Te thin films
L. Mulder, C. Castenmiller, F. J. Witmans +5
High quality thin films of the topological insulator (BiSb)Te have been deposited on SrTiO (111) by molecular beam epitaxy. Their electronic structure w…
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…
