Accessibility of doping ranges of semiconductors by terahertz spectroscopy
Joshua Hennig, Jens Klier, Stefan Duran +4
While established semiconductor measurement techniques such as four-point probe or capacitance-voltage measurements require a physical contact to the material, terahertz spectrosco…
Unsupervised Learning for Industrial Defect Detection: A Case Study on Shearographic Data
Jessica Plassmann, Nicolas Schuler, Georg von Freymann +1
Shearography is a non-destructive testing method for detecting subsurface defects, offering high sensitivity and full-field inspection capabilities. However, its industrial adoptio…
Simultaneous Charge Carrier Density Mapping of SiC Epilayers and Substrates with Terahertz Time-Domain Spectroscopy
Joshua Hennig, Jens Klier, Stefan Duran +9
With the growing demand for efficient power electronics, SiC-based devices are progressively becoming more relevant. In contrast to established methods such as the mercury capacita…
Dynamic interfacial effects in ultrathin ferromagnetic bilayers
Anulekha De, Christopher Seibel, Sanjay Ashok +7
We investigate the magnetization dynamics of an ultrathin Co (1.5 nm) /Py (1.5 nm) bilayer system from femtosecond (fs) to nanosecond (ns) timescales. Magnetization dynamics in the…
General simulation method for quantum-sensing systems
Felix Riexinger, Mirco Kutas, Björn Haase +2
Quantum sensing encompasses highly promising techniques with diverse applications including noise-reduced imaging, super-resolution microscopy as well as imaging and spectroscopy i…
Weak localisation enhanced ultrathin scattering media
Ruben Pompe, Dominic Meiers, Walter Pfeiffer +1
The brilliant white appearance of ultrathin scattering media with low refractive index contrast and the underlying radiative transport phenomena fascinate scientists for more than…
Observation of a charge-2 photonic Weyl point in the infrared
Sachin Vaidya, Jiho Noh, Alexander Cerjan +1
Weyl points are robust point degeneracies in the band structure of a periodic material, which act as monopoles of Berry curvature. They have been at the forefront of research in th…
Spin-Wave Optical Elements: Towards Spin-Wave Fourier Optics
Marc Vogel, Burkard Hillebrands, Georg von Freymann
We perform micromagnetic simulations to investigate the propagation of spin-wave beams through spin-wave optical elements. Despite spin-wave propagation in magnetic media being str…
