Abstract Traditional power electronic equipment has long relied on discrete active and passive components, with performance enhancements often requiring trade-offs. Despite technological advancements, manufacturing processes remain labor-intensive and largely unchanged for decades. The advent of wide-bandgap (WBG) power semiconductor devices, such as silicon carbide (SiC) and gallium nitride (GaN), has significantly reduced conduction and switching […]

Abstract There is simultaneously an interest for more energy-efficient hardware in challenging applications, as well as a drive to overhaul the von Neumann architecture toward more brain-like architectures. Compute-in-Memory (CIM) is one emerging paradigm addressing key memory bottlenecks such as bandwidth limitations, access latency, and high data movement energy in conventional computing platforms. In part […]

Abstract Engineering robust, solid-state quantum systems is amongst the most pressing challenges to realise scalable quantum photonic circuitry. While several 3D systems (such as diamond or gallium arsenide) have been thoroughly studied, solid state emitters in van der Waals (vdW) and two dimensional (2D) materials are still in their infancy. In this presentation, I will […]

Abstract Redox-based resistive switching random access memory (ReRAM) which is frequently discussed as a promising non-volatile memory as well as a central element in novel neuromorphic computing applications, is typically integrated in 1-transistor-1-resistor (1T1R) structures. While the access transistor is required as a selective device and acts as an effective current compliance during SET, it […]
