Dataset

This is a data set for the article: 'Electric-field control of zero-dimensional topological states in ultranarrow germanene nanoribbons'. This data set includes the data for all the experimental figures of the main text as well as the supplementary material, that is measured by the PIN research group at the University of Twente. The article is written in collaboration with the Institute for Theoretical Physics from Utrecht University, who have uploaded the codes necessary to compute all theoretical figures on their own data server. Below is the abstract for the article:


Reversible, all-electric control of symmetry-protected zero-dimensional modes has been a longstanding

goal. In buckled honeycomb lattices, a perpendicular field couples to the staggered sublattice

potential providing the required handle. We combine scanning tunneling microscopy and

tight-binding theory to switch zero-dimensional topological end states reversibly on and o! in ultranarrow

germanene nanoribbons by tuning the electric field in the tunnel junction. Increasing the field

switches o! the end modes of topological two-hexagon wide ribbons, while the same field switches on

zero-dimensional states in initially trivial three- and four-hexagon wide ribbons. This atomic scale

platform realizes a proof-of-principle for a zero-dimensional topological field e!ect device, opening

a path for ultrasmall memory, controllable qubits, and neuromorphic architectures.
