Excited State Spectroscopy of Boron Vacancy Defects in Hexagonal Boron Nitride using Time-Resolved Optically Detected Magnetic Resonance
Simon Baber, Ralph N. E. Malein, Prince Khatri +5
We report optically detected magnetic resonance (ODMR) measurements of an ensemble of spin-1 negatively charged boron vacancies in hexagonal boron nitride. The photoluminescence de…
Water-based and Biocompatible 2D Crystal Inks: from Ink Formulation to All- Inkjet Printed Heterostructures
D. McManus, S. Vranic, F. Withers +10
Fully exploiting the properties of 2D crystals requires a mass production method able to produce heterostructures of arbitrary complexity on any substrate, including plastic. Solut…
Heterostructures produced from nanosheet-based inks
F. Withers, H. Yang, L. Britnell +13
The new paradigm of heterostructures based on two-dimensional (2D) atomic crystals has already led to the observation of exciting physical phenomena and creation of novel devices.…
Two-dimensional metal-chalcogenide films in tunable optical microcavities
S. Schwarz, S. Dufferwiel, P. M. Walker +12
Quasi-two-dimensional (2D) films of layered metal-chalcogenides have attractive optoelectronic properties. However, photonic applications of thin films may be limited owing to weak…
Accurate determination of electron-hole asymmetry and next-nearest neighbor hopping in graphene
A. Kretinin, G. L. Yu, R. Jalil +7
The next-nearest neighbor hopping term t' determines a magnitude and, hence, importance of several phenomena in graphene, which include self-doping due to broken bonds and the Klei…
Novel highly conductive and transparent graphene based conductors
Ivan Khrapach, Freddie Withers, Thomas H. Bointon +4
Future wearable electronics, displays and photovoltaic devices rely on highly conductive, transparent and yet mechanically flexible materials. Nowadays indium tin oxide (ITO) is th…
Electrochemical doping of graphene
A. A. Kaverzin, S. M. Strawbridge, A. S. Price +3
The electrical properties of graphene are known to be modified by chemical species that interact with it. We investigate the effect of doping of graphene-based devices by toluene (…
Electron properties of fluorinated single-layer graphene transistors
Freddie Withers, Marc Dubois, Alexander K. Savchenko
We have fabricated transistor structures using fluorinated single-layer graphene flakes and studied their electronic properties at different temperatures. Compared with pristine gr…
