Equivalence of pseudogap and pairing energy in a cuprate high-temperature superconductor
Jiasen Niu, Maialen Ortego Larrazabal, Thomas Gozlinski +8
The pseudogap stands out in the phase diagram of the cuprate high-temperature superconductors because its origin and relationship to superconductivity remain elusive. The origin of…
Self-supervised learning for denoising quasiparticle interference data
Ilse S. Kuijf, Willem O. Tromp, Tjerk Benschop +4
Tunneling spectroscopy is an important tool for the study of both real-space and momentum-space electronic structure of correlated electron systems. However, such measurements ofte…
Direct visualization of quasiparticle concentration around superconducting vortices
Jian-Feng Ge, Koen M. Bastiaans, Jiasen Niu +3
Bogoliubov quasiparticles play a crucial role in understanding the behavior of a superconductor, and in achieving reliable operations of superconducting quantum circuits. Diagnosis…
Puddle formation, persistent gaps, and non-mean-field breakdown of superconductivity in overdoped (Pb,Bi)2Sr2CuO6+δ
Willem O. Tromp, Tjerk Benschop, Jian-Feng Ge +14
The cuprate high-temperature superconductors exhibit many unexplained electronic phases, but it was often thought that the superconductivity at sufficiently high doping is governed…
Single-electron charge transfer into putative Majorana and trivial modes in individual vortices
Jian-Feng Ge, Koen M. Bastiaans, Damianos Chatzopoulos +6
Majorana bound states are putative collective excitations in solids that exhibit the self-conjugate property of Majorana fermions - they are their own antiparticles. In iron-based…
Imaging moiré deformation and dynamics in twisted bilayer graphene
Tobias A. de Jong, Tjerk Benschop, Xingchen Chen +5
In twisted bilayer graphene (TBG) a moiré pattern forms that introduces a new length scale to the material. At the 'magic' twist angle of 1.1°, this causes a flat band to form, yie…
Fabrication of on-chip probes for double-tip scanning tunneling microscopy
Maarten Leeuwenhoek, Freek Groenewoud, Kees van Oosten +3
Reduction of the inter-probe distance in multi-probe and double-tip STM down to the nanometer scale has been a longstanding and technically difficult challenge. Recent multi-probe…
Measuring local moiré lattice heterogeneity of twisted bilayer graphene
Tjerk Benschop, Tobias A. de Jong, Petr Stepanov +5
We introduce a new method to continuously map inhomogeneities of a moiré lattice and apply it to large-area topographic images we measure on open-device twisted bilayer graphene (T…
Direct evidence for flat bands in twisted bilayer graphene from nano-ARPES
Simone Lisi, Xiaobo Lu, Tjerk Benschop +21
Transport experiments in twisted bilayer graphene revealed multiple superconducting domes separated by correlated insulating states. These properties are generally associated with…
Charge trapping and super-Poissonian noise centers in a cuprate high-temperature superconductor
K. M. Bastiaans, D. Cho, T. Benschop +7
The electronic properties of cuprate high temperature superconductors in their normal state are very two-dimensional: while transport in the ab plane is perfectly metallic, it is i…
Amplifier for scanning tunneling microscopy at MHz frequencies
K. M. Bastiaans, T. Benschop, D. Chatzopoulos +4
Conventional scanning tunneling microscopy (STM) is limited to a bandwidth of circa 1kHz around DC. Here, we develop, build and test a novel amplifier circuit capable of measuring…
