ABSTRACT:
Germanium radiation detectors are manufactured by diffusing lithium into high purity p-type germanium. The diffusion is most readily accomplished from a lithium-lead-bismuth alloy at approximately 430.degree. and is monitored by a quartz half cell containing a standard composition of this alloy.
Detectors having n-type cores may be constructed by converting high purity p-type germanium to n-type by a lithium diffusion and subsequently diffusing some of the lithium back out through the surface to create a deep p-n junction.
Coaxial germanium detectors comprising deep p-n junctions are produced by the lithium diffusion process.
