• To experimentally verify the performance in silicon and establish semiconductor similarity relations.

Main Methods:

• Development of a novel readout structure for signal-processing-in-the-element detectors.
• Experimental validation using silicon (Si) as the semiconductor material.
• Derivation of similarity relations between silicon and mercury cadmium telluride (HgCdTe) for performance comparison.

Main Results:

• The new readout structure achieved a modulation transfer function 3.5 dB better than current structures.
• Experimental verification in silicon confirmed the performance enhancement.
• Similarity relations were established, allowing for performance prediction across different semiconductor materials.

Conclusions:
