Contact-free charge carrier density determination of doped sub-μm thin cubic GaN layers with terahertz time-domain spectroscopy
Joshua Hennig, Mario F. Zscherp, Silas A. Jentsch +11
As cubic GaN is a promising material for optoelectronic applications, its layers need to be precisely doped to realize the desired properties. While contact-based methods are estab…
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…
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…
Wide-range resistivity characterization of semiconductors with terahertz time-domain spectroscopy
Joshua Hennig, Jens Klier, Stefan Duran +9
Resistivity is one of the most important characteristics in the semiconductor industry. The most common way to measure resistivity is the four-point probe method, which requires ph…
Phase-quadrature quantum imaging with undetected photons
Björn Erik Haase, Joshua Hennig, Mirco Kutas +4
Sensing with undetected photons allows access to spectral regions with simultaneous detection of photons of another region and is based on nonlinear interferometry. To obtain the f…
