Abstract

Advanced quantum technologies require reliable and scalable nanofabrication processes for the realization of high-quality cryogenic devices. In this seminar, I will present my experience in semiconductor process development, superconducting quantum device fabrication, and hybrid material integration for cryogenic platforms.

The talk will cover the development and optimization of fabrication workflows for Josephson junction-based devices, low-temperature ALD processes compatible with sensitive quantum materials, and integration strategies for hybrid quantum systems based on 2D materials and HgTe quantum wells. I will also discuss process reproducibility, device integration, and cryogenic electrical characterization, with an emphasis on reliable fabrication approaches and collaborative multi-user research environments.
