Tunable quantum dots from atomically precise graphene nanoribbons using a multi-gate architecture
Jian Zhang, Oliver Braun, Gabriela Borin Barin +14
Atomically precise graphene nanoribbons (GNRs) are increasingly attracting interest due to their largely modifiable electronic properties, which can be tailored by controlling thei…
Optimized Graphene Electrodes for contacting Graphene Nanoribbons
Oliver Braun, Jan Overbeck, Maria El Abbassi +12
Atomically precise graphene nanoribbons are a promising emerging class of designer quantum materials with electronic properties that are tunable by chemical design. However, many c…
Benchmark and application of unsupervised classification approaches for univariate data
Maria El Abbassi, Jan Overbeck, Oliver Braun +3
Unsupervised machine learning, and in particular data clustering, is a powerful approach for the analysis of datasets and identification of characteristic features occurring throug…
Controlled quantum dot formation in atomically engineered graphene nanoribbons field-effect transistors
Maria El Abbassi, Mickael Perrin, Gabriela Borin Barin +12
Graphene nanoribbons (GNRs) have attracted a strong interest from researchers worldwide, as they constitute an emerging class of quantum-designed materials. The major challenges to…
A Universal Length-Dependent Vibrational Mode in Graphene Nanoribbons
Jan Overbeck, Gabriela Borin Barin, Colin Daniels +13
Graphene nanoribbons (GNRs) have attracted considerable interest as their atomically tunable structure makes them promising candidates for future electronic devices. However, obtai…
In-situ strain tuning in hBN-encapsulated graphene electronic devices
Lujun Wang, Simon Zihlmann, Andreas Baumgartner +5
Using a simple setup to bend a flexible substrate, we demonstrate deterministic and reproducible in-situ strain tuning of graphene electronic devices. Central to this method is the…
Photocurrents in a Single InAs Nanowire/ Silicon Heterojunction
Andreas Brenneis, Jan Overbeck, Julian Treu +7
We investigate the optoelectronic properties of single indium arsenide nanowires, which are grown vertically on p-doped silicon substrates. We apply a scanning photocurrent microsc…
