The goal of the project is to develop detectors with excellent price-quality ratio and/or extremely high sensitivity enabling e.g. improvements in night vision and in the detection limits of various scientific measurement equipment (e.g. detection of even smaller tumors). This breakthrough is made possible by the noteworthy results achieved in the previous project: 1) a nanostructure that eliminates reflection losses, 2) surface passivation, which enables electrically high-quality interfaces, and 3) an almost lossless charge collection mechanism based on high charge density ALD thin films. Here these innovations are further refined towards higher TRL-levels and commercial breakthrough potential using two different approaches: 1) in order to achieve a competitive price-quality ratio in consumer applications, development of Ge-on-Si detectors is done and 2) extreme sensitivity is pursued with the development of detectors based on high-purity Ge crystals.
