Raman Fingerprints of Graphene Produced by Anodic Electrochemical Exfoliation
Vaiva Nagyte, Daniel J. Kelly, Alexandre Felten +11
Electrochemical exfoliation is one of the most promising methods for scalable production of graphene. However, limited understanding of its Raman spectrum as well as lack of measur…
Low-temperature electroluminescence excitation mapping of excitons and trions in short channel monochiral carbon nanotube device
Marco Gaulke, Alexander Janissek, Naga Anirudh Peyyety +12
Single walled carbon nanotubes as emerging quantum-light sources may fill a technological gap in silicon photonics due to their potential use as near infrared, electrically driven,…
Light emission, light detection and strain sensing with nanocrystalline graphene
Adnan Riaz, Feliks Pyatkov, Asiful Alam +7
Graphene is of increasing interest for optoelectronic applications exploiting light detection, light emission and light modulation. Intrinsically light matter interaction in graphe…
Dielectrophoretic Assembly of High-Density Arrays of Individual Graphene Devices for Rapid Screening
Aravind Vijayaraghavan, Calogero Sciascia, Simone Dehm +4
We establish the use of dielectrophoresis for the directed parallel assembly of individual flakes and nanoribbons of few-layer graphene into electronic devices. This is a bottom-up…
High Impedance Granular Aluminum Ring Resonators
Mahya Khorramshahi, Martin Spiecker, Patrick Paluch +10
Superconducting inductors with impedance surpassing the resistance quantum, i.e., superinductors, are important for quantum technologies because they enable the development of prot…
Electroluminescence from chirality-sorted (9,7)-semiconducting carbon nanotube devices
Martin H. P. Pfeiffer, Ninette Stürzl, Christoph W. Marquardt +6
We have measured the electroluminescence and photoluminescence of (9,7) semiconducting carbon nanotube devices and demonstrate that the electroluminescence wavelength is determined…
