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,…
Polarization doping ab initio verification of the concept charge conservation and nonlocality
Ashfaq Ahmad, Pawel Strak, Pawel Kempisty +10
In this work, we study the emergence of polarization doping in AlxGa1-xN layers with graded composition from a theoretical viewpoint. We demonstrate that the charge conservation la…
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…
