Electrostatically-induced strain of graphene on GaN nanorods
Jakub Kierdaszuk, Rafał Bożek, Tomasz Stefaniuk +11
Few-layer graphene deposited on semiconductor nanorods separated by undoped spacers has been studied in perspective for the fabrication of stable nanoresonators. We show that an ap…
Pseudomagnetic fields and strain engineering: graphene on GaN nanowires
Jakub Kierdaszuk, Paweł Dąbrowski, Maciej Rogala +11
Gallium nitride nanowire and nanorod substrates with different morphology are prospective platforms allowing to control the local strain distribution in graphene films top of them,…
Highly effective gating of graphene on GaN
Jakub Kierdaszuk, Ewelina Rozbiegała, Karolina Piętak +8
By using four layered graphene/gallium nitride (GaN) Schottky diodes with an undoped GaN spacer, we demonstrate highly effective gating of graphene at low bias rendering this type…
Computational Doppler-limited dual-comb spectroscopy with a free-running all-fiber laser
Łukasz A. Sterczewski, Aleksandra Przewłoka, Wawrzyniec Kaszub +1
Dual-comb spectroscopy has emerged as an indispensable analytical technique in applications that require high resolution and broadband coverage within short acquisition times. Its…
Properties of graphene deposited on GaN nanowires: influence of nanowire roughness, self-induced nanogating and defects
Jakub Kierdaszuk, Piotr Kaźmierczak, Justyna Grzonka +8
We present detailed Raman studies of graphene deposited on gallium nitride nanowires with different variations in height. Our results show that different density and height of nano…
Surface-enhanced Raman scattering in graphene deposited on AlGaN/GaN axial heterostructure nanowires
Jakub Kierdaszuk, Mateusz Tokarczyk, Krzysztof M. Czajkowski +11
The surface-enhanced Raman scattering in graphene deposited on AlxGa1-xN/GaN axial heterostructure nanowires was investigated. The intensity of graphene Raman spectra was found not…
Mutually Unbiased Bases and Complementary Spin 1 Observables
Pawel Kurzynski, Wawrzyniec Kaszub, Mikolaj Czechlewski
The two observables are complementary if they cannot be measured simultaneously, however they become maximally complementary if their eigenstates are mutually unbiased. Only then t…
