This detector is designed with a high-purity 'denuded zone' adjacent to a radiation-absorbing region. The innovative design incorporates an internally generated electric field, which significantly enhances the lifetime of charge carriers by reducing recombination effects. Additionally, the inclusion of a wider bandgap surface passivation region effectively traps impurities, optimizing the detector's performance.

The second patent, the **Heterojunction Photodiode Array**, comprises a sophisticated array of photovoltaic radiation detectors. This invention utilizes a substrate transparent to relevant radiation wavelengths and a compositionally graded p-type HgCdTe base layer. The array is designed to efficiently collect charge carriers through multiple regions formed in the wide bandgap cap layer, which prevents lateral diffusion of charge carriers. These inventions showcase Rosbeck's expertise in developing advanced detection technologies.
