Manipulating carbon related spin defects in boron nitride by changing the MOCVD growth temperature
Jakub Iwański, Jakub Kierdaszuk, Arkadiusz Ciesielski +3
A common solution for precise magnetic field sensing is to employ spin-active defects in semiconductors, with the NV center in diamond as prominent example. However, the three-dime…
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…
Volumetric incorporation of NV diamond emitters in nanostructured F2 glass magneto-optical fiber probes
Adam Filipkowski, Mariusz Mrózek, Grzegorz Stępniewski +8
Integration of optically-active nanodiamonds with glass fibers is a powerful method of scaling of diamond magnetic sensing functionality. We propose a novel approach for integratio…
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…
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…
Surface-enhanced Raman scattering of graphene caused by self-induced nanogating by GaN nanowire array
Jakub Kierdaszuk, Piotr Kaźmierczak, Rafał Bożek +9
A constant height of gallium nitride (GaN) nanowires with graphene deposited on them is shown to have a strong enhancement of Raman scattering, whilst variable height nanowires fai…
Enhanced Raman scattering and weak localization in graphene deposited on GaN nanowires
Jakub Kierdaszuk, Piotr Kaźmierczak, Aneta Drabińska +8
The influence of GaN nanowires on the optical and electrical properties of graphene deposited on them was studied using Raman spectroscopy and microwave induced electron transport…
