The chemical effect goes resonant – a full quantum mechanical approach on TERS
Lately, experimental evidence of unexpectedly extremely high spatial resolution of tip-enhanced Raman scattering (TERS) has been demonstrated. Theoretically, two different contributions are discussed:...
PublikationenHomoepitaxy of ZnO by pulsed-laser deposition
ZnO thin films were grown homoepitaxially on O-face ZnO single crystals by pulsed-laser deposition. The ZnO substrates grown by the hydrothermal method were heat-treated in oxygen ambient at 1000 °C for...
PublikationenQuantum Confined Stark Effect of excitons localized at very thin InAs layers embedded in GaAs
InAs monolayers (1.0–1.7 ML) embedded in GaAs can effectively bind Frenkel-like excitons in the perpendicular direction and have efficient optical heavy hole hh–e and light hole lh–e transitions...
PublikationenDielectric function effects due to isovalent monolayers of III-elements buried in GaAs, GaP, and AlGaAs
Ellipsometric measurements have been made at room temperature on MOVPE-grown InAs monolayers (ML) (0.5 to 1 ML) in GaAs around the fundamental gap E0 and the critical point (CP) E1 of the material GaAs...
PublikationenDifferential response of liver sinusoidal endothelial cells and hepatocytes to oleic and palmitic acid revealed by Raman and CARS imaging
Excess circulating fatty acids contribute to endothelial dysfunction that subsequently aggravates the metabolic conditions such as fatty liver diseases. However, the exact mechanism of this event is not...
PublikationenDeep learning a boon for Biophotonics?
This review covers original articles using deep learning in the biophotonic field published in the last years. In these years deep learning, which is a subset of machine learning mostly based on artificial...
PublikationenRapid detection of the aspergillosis biomarker triacetylfusarinine C using interference-enhanced Raman spectroscopy
Triacetylfusarinine C (TAFC) is a siderophore produced by certain fungal species and might serve as a highly useful biomarker for the fast diagnosis of invasive aspergillosis. Due to its renal elimination,...
PublikationenCaF2 – an ideal substrate material for infrared spectroscopy?
CaF2 seems to be the ideal substrate material for organic and biological layers, since its refractive index is very similar to that of these materials. As a consequence of this similarity, the baseline...
PublikationenOne Health Approach for Identification of Sources/Reservoir of Multidrug Resistant Bacteria in Wild Animals and their Environment
Bacteria such as extra-intestinal pathogenic E. coli (ExPEC) and methicillin-resistant S. aureus (MRSA) are important opportunistic pathogens. They might belong to pandemic, epidemic and/or sporadic clones....
PublikationenProbabilistic motional averaging
In a continuous measurement scheme a spin-1/2 particle can be measured and simultaneously driven by an external resonant signal. When the driving is weak, it does not prevent the particle wave-function...
