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…
Temperature induced giant shift of phonon energy in epitaxial boron nitride layers
Jakub Iwański, Piotr Tatarczak, Mateusz Tokarczyk +5
The recent progress in the growth of large-area boron nitride epilayers opens up new possibilities for future applications. However, it remains largely unclear how weakly attached…
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,…
Upconverted electroluminescence via Auger scattering of interlayer excitons in van der Waals heterostructures
J. Binder, J. Howarth, F. Withers +11
The intriguing physics of carrier-carrier interactions, which likewise affect the operation of light emitting devices, stimulate the research on semiconductor structures at high de…
Optical response of monolayer, few-layer and bulk tungsten disulfide
Maciej R. Molas, Karol Nogajewski, Artur O. Slobodeniuk +3
We present a comprehensive optical study of thin films of tungsten disulfide (WS) with layer thicknesses ranging from mono- to octalayer and in the bulk limit. It is shown that…
Sub-bandgap voltage electroluminescence and magneto-oscillations in a WSe2 light-emitting van der Waals heterostructure
J. Binder, F. Withers, M. R. Molas +8
We report on experimental investigations of an electrically driven WSe2 based light-emitting van der Waals heterostructure. We observe a threshold voltage for electroluminescence s…
