Electronic transport in graphene with out-of-plane disorder
Real-world samples of graphene often exhibit various types of out-of-plane disorder-ripples, wrinkles and folds-introduced at the stage of growth and transfer processes. These complex out-of-plane defects resulting from the interplay between self-adhesion ...
Berlin2024Functionalized Å-scale Pores in Graphene for Carbon Capture
Single-layer graphene, hosting a high density of functionalized molecular-sieving atom-thick pores, is considered to be an excellent material for gas separation membranes. These functionalized atom-thick pores enable the shortest transport pathway across t ...
EPFL2024Magneto-Thermoelectric Transport in Graphene Quantum Dot with Strong Correlations
Disorder at etched edges of graphene quantum dots (GQD) enables random all-to-all interactions between localized charges in partially filled Landau levels, providing a potential platform to realize the Sachdev-Ye-Kitaev (SYK) model. We use quantum Hall edg ...
2024Micropreparative Gel Electrophoresis for Purification of Nanoscale Bioconjugates
Ardemis Anoush Boghossian, Sayyed Hashem Sajjadi, Yahya Rabbani, Shang-Jung Wu, Vitalijs Zubkovs
Conventional techniques for purifying macromolecular conjugates often require complex and costly installments that are inaccessible to most laboratories. In this work, we develop a one-step micropreparative method based on a trilayered polyacrylamide gel e ...
2024Electrochemical-repaired porous graphene membranes for precise ion-ion separation
Kumar Varoon Agrawal, Kuang-Jung Hsu, Shuqing Song, Kangning Zhao, Heng-Yu Chi, Zongyao Zhou
The preparation of atom-thick porous lattice hosting & Aring;-scale pores is attractive to achieve a large ion-ion selectivity in combination with a large ion flux. Graphene film is an ideal selective layer for this if high-precision pores can be incorpora ...
Nature Portfolio2024Nanolithography of the nanocorral structure of chemisorbed oxygen atoms on the graphitic lattice
Kumar Varoon Agrawal, Shaoxian Li
Controlled atomic patterning is an attractive tool to fine tune properties of graphitic lattice. Several O-functionalized derivatives of graphitic lattice have been widely studied, e.g., graphene oxide, reduced graphene oxide, and functionalized carbon nan ...
Oxford2024On-Surface Synthesis of Edge-Extended Zigzag Graphene Nanoribbons
Graphene nanoribbons (GNRs) have gained significant attention in nanoelectronics due to their potential for precise tuning of electronic properties through variations in edge structure and ribbon width. However, the synthesis of GNRs with highly sought-aft ...
Weinheim2023From defect to effect: controlling electronic transport in chevron graphene nanoribbons
Oleg Yazyev, Kristians Cernevics
While bottom-up synthesis allows for precise control over the properties of graphene nanoribbons (GNRs), the use of certain precursor molecules can result in edge defects, such as missing benzene rings that resemble a 'bite'. We investigate the adverse eff ...
IOP Publishing Ltd2023A versatile platform for graphene nanoribbon synthesis, electronic decoupling, and spin polarized measurements
Johannes Schwenk, Donat Fabian Natterer
The on-surface synthesis of nano-graphenes has led the charge in prototyping structures with perspectives beyond silicon-based technology. Following reports of open-shell systems in graphene-nanoribbons (GNRs), a flurry of research activity was directed at ...
