Germanium orthogonal strip detectors with amorphous-semiconductor contacts

Germanium orthogonal strip detectors have been produced using amorphous-semiconductor contacts. The amorphous-semiconductor contact fabrication process is relatively simple, and it is capable of producing fine-pitched electrode structures. The bipolar blocking behavior of the amorphous-semiconductor contact permits its use on both sides of a detector, replacing conventional B ion implanted and Li diffused contacts. A 5×5 orthogonal strip detector has been produced using this technique. Experimental results from this detector are presented
