Direct Characterization of Band Bending in GaP/Si(001) Heterostructures with Hard X-ray Photoelectron Spectroscopy
Martin Schmid, Kunie Ishioka, Andreas Beyer +9
We apply hard X-ray photoelectron spectroscopy (HAXPES) to investigate the electronic structures in ~50-nm thick epitaxial GaP layers grown on Si(001) under different conditions. D…
Second-harmonic generation as probe for structural and electronic properties of buried GaP/Si(001) interfaces
K. Brixius, A. Beyer, J. Güdde +4
Optical second-harmonic generation is demonstrated to be a sensitive probe of the buried interface between the lattice matched semiconductors gallium phosphide and silicon with (00…
Model potential for the description of metal/organic interface states
N. Armbrust, F. Schiller, J. Güdde +1
We present an analytical one-dimensional model potential for the description of electronic interface states that form at the interface between a metal surface and flat-lying adlaye…
Chemoselective Reactivity of Bifunctional Cyclooctynes on Si(001)
Marcel Reutzel, Niels Münster, Marcus A. Lipponer +4
Controlled organic functionalization of silicon surfaces as integral part of semiconductor technology offers new perspectives for a wide range of applications. The high reactivity…
Second-harmonic imaging microscopy for time-resolved investigations of transition metal dichalcogenides
J. E. Zimmermann, B. Li, J. Hone +2
Two-dimensional transition metal dichalcogenides (TMDC) have shown promise for various applications in optoelectronics and so-called valleytronics. Their operation and performance…
Intrinsic coherent acoustic phonons in indirect band gap semiconductors Si and GaP
Kunie Ishioka, Avinash Rustagi, Ulrich Hoefer +2
We report on the intrinsic optical generation and detection of coherent acoustic phonons at (001)-oriented bulk Si and GaP without metallic phonon transducer structures. Photoexcit…
