BA: Evaluation of the conductance method for determining the interface state densities of 4H-SiC-based MOS structures
Lukas Fehler — The aim of this thesis was to evaluate the conductance method using a Keysight E4980A Precision LCR Meter for determining the interface state density in 4H-SiC-based MOS structures. To this end, n-type 4H-SiC MOS capacitors with a 55 nm thick SiO2 layer were characterized at room temperature of 300 K by both […]

BA: Realization and optimization of ODMR measurements on V2 silicon vacancies in 4H-SiC pin diodes
Sebastian Rohrseitz – Due to the advantageous combination of optically active color centers with established semiconductor manufacturing processes, 4H-SiC represents a promising material platform for applications in quantum technology. The integration of these color centers into a p-i-n diode enables a significant reduction in the optical linewidth by stabilizing the charge environment of the point […]Sebastian Rohrseitz – Due to the advantageous combination of optically active color centers with established semiconductor manufacturing processes, 4H-SiC represents a promising material platform for applications in quantum technology.

MA: Edge Termintion in Superjunction
Description Superjunction devices have already demonstrated in silicon technologies that the previous “silicon limit” can be exceeded. They allow for a smaller chip area per device and/or a reduction of the on-resistance compared to conventional designs at the same design voltage. The industry is increasingly moving towards silicon carbide (SiC) for high-voltage applications. Due to […]

MA: Simulation-based analysis of error effects in the characterization of ohmic contacts on 4H-SiC using CBKR test structures
Fabian Schellenberger — This work investigates the Cross bridge Kelvin resistor (CBKR) structure for the measurement of specific contact resistances 𝜌c on 4H-SiC. The influences that reduce the measurement precision of this test structure are investigated using a simulation-based approach. The information gained with these simulations allow for the extraction of design rules for improved […]Fabian Schellenberger — This work investigates the Cross bridge Kelvin resistor (CBKR) structure for the measurement of specific contact resistances 𝜌c on 4H-SiC.
