Photoemission study and band alignment of GaN passivation layers on GaInP heterointerface
S. Shekarabi, M. A. Zare Pour, H. Su +6
III-V semiconductor-based photoelectrochemical (PEC) devices show the highest solar-to-electricity or solar-to-fuel conversion efficiencies. GaInP is a relevant top photoabsorber l…
Band energy diagrams of n-GaInP/n-AlInP(100) surfaces and heterointerfaces studied by X-ray photoelectron spectroscopy
Mohammad Amin Zare Pour, Oleksandr Romanyuk, Dominik C. Moritz +9
Lattice matched n-type AlInP(100) charge selective contacts are commonly grown on n-p GaInP(100) top absorbers in high-efficiency III-V multijunction solar or photoelectrochemical…
Combining advanced photoelectron spectroscopy approaches to analyse deeply buried GaP(As)/Si(100) interfaces: Interfacial chemical states and complete band energy diagrams
O. Romanyuk, A. Paszuk, I. Gordeev +14
The epitaxial growth of the polar GaP(100) on the nonpolar Si(100) substrate suffers from inevitable defects at the antiphase domain boundaries, resulting from mono-atomic steps on…
The impact of non-ideal surfaces on the solid-water interaction: a time-resolved adsorption study
Matthias M. May, Helena Stange, Jonas Weinrich +2
The initial interaction of water with semiconductors determines the electronic structure of the solid-liquid interface. The exact nature of this interaction is, however, often unkn…
Monolithic Photoelectrochemical Device for 19% Direct Water Splitting
Wen-Hui Cheng, Matthias H. Richter, Matthias M. May +6
Recent rapid progress in efficiencies for solar water splitting by photoelectrochemical devices has enhanced its prospects to enable storable renewable energy. Efficient solar fuel…
Comment on pyramidal structure formation at the interface between III/V semiconductors and silicon
Thomas Hannappel, Oliver Supplie, Sebastian Bruckner +3
GaP/Si(100) is considered as pseudomporphic virtual substrate for III/V-on-Si integration in order to reduce defects related to polar-on-nonpolar heteroepitaxy. The atomic structur…
Efficient Direct Solar-to-Hydrogen Conversion by In Situ Interface Transformation of a Tandem Structure
Matthias M. May, Hans-Joachim Lewerenz, David Lackner +2
Photosynthesis is nature's route to convert intermittent solar irradiation into storable energy, while its use for an industrial energy supply is impaired by low efficiency. Artifi…
The interface of GaP(100) and H2O studied by photoemission and reflection anisotropy spectroscopy
Matthias M May, Oliver Supplie, Christian Höhn +3
We study the initial interaction of adsorbed H2O with P-rich and Ga-rich GaP(100) surfaces. Atomically well defined surfaces are prepared by metal-organic vapour phase epitaxy and…
Enhancement of the Zero Phonon Line emission from a Single NV-Center in a Nanodiamond via Coupling to a Photonic Crystal Cavity
Janik Wolters, Andreas W. Schell, Güter Kewes +7
Using a nanomanipulation technique a nanodiamond with a single nitrogen vacancy center is placed directly on the surface of a gallium phosphide photonic crystal cavity. A Purcell-e…
