PAMBE growth of GaN nanowires on metallic ZrN buffers -- a critical impact of ZrN layer thickness on the growth temperature

Karol Olszewski, Zbigniew R. Zytkiewicz, Aleksandra Wierzbicka +2

An impact of thin metallic ZrN layers on Si and sapphire wafers on substrate temperature during MBE growth of GaN nanowires is studied. Using nucleation kinetics of GaN as a sensit…

Strain distribution in GaN/AlN superlattices grown on AlN/sapphire templates: comparison of X-ray diffraction and photoluminescence studies

Aleksandra Wierzbicka, Agata Kaminska, Kamil Sobczak +5

Series of GaN/AlN superlattices (SLs) with various periods and the same thicknesses of GaN quantum wells and AlN barriers have been investigated. X-ray diffraction, photoluminescen…

ZrN nucleation layer provides backside ohmic contact to MBE-grown GaN nanowires

Stanislav Tiagulskyi, Roman Yatskiv, Marta Sobanska +3

Self-assembled GaN nanowires are typically grown on Si substrates with convenient nucleation layers. Light-emitting devices based on arrays of GaN nanowires require that the nuclea…

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…
