Epitaxial hexagonal boron nitride for hydrogen generation by radiolysis of interfacial water
Johannes Binder, Aleksandra Krystyna Dąbrowska, Mateusz Tokarczyk +5
Hydrogen is an important building block in global strategies towards a future green energy system. To make this transition possible, intense scientific efforts are needed, also in…
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…
Heteroepitaxial growth of high optical quality, wafer-scale van der Waals heterostrucutres
Katarzyna Ludwiczak, Aleksandra Krystyna Dąbrowska, Johannes Binder +9
Transition metal dichalcogenides (TMDs) are materials that can exhibit intriguing optical properties like a change of the bandgap from indirect to direct when being thinned down to…
Fundamental mechanisms of hBN growth by MOVPE
Krzysztof Pakuła, Aleksandra Dąbrowska, Mateusz Tokarczyk +5
Hexagonal boron nitride is a promising material for many applications ranging from deep UV emission to an ideal substrate for other two dimensional crystals. Although efforts towar…
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…
Fe dopant in ZnO: 2+ vs 3+ valency and ion-carrier s,p-d exchange interaction
J. Papierska, A. Ciechan, P. Bogusławski +16
Dopants of transition metal ions in II-VI semiconductors exhibit native 2+ valency. Despite this, 3+ or mixed 3+/2+ valency of iron ions in ZnO was reported previously. Several con…
MBE growth and characterization of a II-VI distributed Bragg reflector and microcavity lattice-matched to MgTe
J. -G. Rousset, J. Kobak, T. Slupinski +7
We present the realization and characterization of a 20 fold, fully lattice-matched epitaxial distributed Bragg reflector based on (Cd,Zn)Te and (Cd,Zn,Mg)Te layers. We also presen…
