Benchmarking the integration of hexagonal boron nitride crystals and thin films into graphene-based van der Waals heterostructures
Taoufiq Ouaj, Christophe Arnold, Jon Azpeitia +25
We present a benchmarking protocol that combines the characterization of boron nitride (BN) crystals and films with the evaluation of the electronic properties of graphene on these…
Infrared resonance Raman of bilayer graphene: signatures of massive fermions and band structure on the 2D peak
Lorenzo Graziotto, Francesco Macheda, Tommaso Venanzi +14
Few-layer graphene possesses low-energy carriers which behave as massive fermions, exhibiting intriguing properties in both transport and light scattering experiments. Lowering the…
An open-source robust machine learning platform for real-time detection and classification of 2D material flakes
Jan-Lucas Uslu, Taoufiq Ouaj, David Tebbe +8
The most widely used method for obtaining high-quality two-dimensional materials is through mechanical exfoliation of bulk crystals. Manual identification of suitable flakes from t…
Chemically detaching hBN crystals grown at atmospheric pressure and high temperature for high-performance graphene devices
Taoufiq Ouaj, Leonard Kramme, Marvin Metzelaars +7
In this work, we report on the growth of hexagonal boron nitride (hBN) crystals from an iron flux at atmospheric pressure and high temperature and demonstrate that (i) the entire s…
Probing enhanced electron-phonon coupling in graphene by infrared resonance Raman spectroscopy
Tommaso Venanzi, Lorenzo Graziotto, Francesco Macheda +16
We report on resonance Raman spectroscopy measurements with excitation photon energy down to 1.16 eV on graphene, to study how low-energy carriers interact with lattice vibrations.…
High-quality Tailored-edge Cleaving Using Aberration-corrected Bessel-like Beams
Michael Jenne, Daniel Flamm, Taofiq Ouaj +7
We report on the usage of ultrashort laser pulses in form of aberration-corrected Bessel-like beams for laser cutting of glass with bevels. Our approach foresees to incline the mat…
Fractional quantum Hall effect in CVD-grown graphene
M. Schmitz, T. Ouaj, Z. Winter +6
We show the emergence of fractional quantum Hall states in dry-transferred chemical vapor deposition (CVD) derived graphene assembled into heterostructures for magnetic fields from…
Tailoring mechanically-tunable strain fields in graphene
M. Goldsche, J. Sonntag, T. Khodkov +7
There are a number of theoretical proposals based on strain engineering of graphene and other two-dimensional materials, however purely mechanical control of strain fields in these…
