The conventional coaxial germanium detector is often referred to as Pure Ge, HPGe, Intrinsic Ge, or Hyperpure Ge. Regardless of the superlative used, the detector is basically a cylinder of germanium with an n-type contact on the outer surface, and a p-type contact on the surface of an axial well.

Germanium detectors are semiconductor diodes having a p-i-n structure in which the intrinsic (I) region is sensitive to ionizing radiation, particularly X rays and gamma rays. Charge carriers, produced by the interaction of X and gamma rays in the intrinsic region, are swept by the electric field to the P and N electrodes where are collected.

detector while the p+ contact is applied in case of an n-type crystal. The n-type coaxial detectors are often called reverse electrode detectors. The reverse bias requires a positive outside potential for a p-type and a negative potential for an n-type relative to the central electric potential. n+ contact p-type p+ p+ contact n-type n+ Fig. 8.7.

Ge, HPGe, Intrinsic Ge, or Hyperpure Ge. Regardless of the superlative used, the detector is basically a cylinder of germanium with an n-type contact on the outer surface, and a p-type contact on the surface of an axial well. The germanium has a net impurity level of around 1010 atoms/cc so that with moderate reverse bias, the entire volume

P-N Junction One of the crucial keys to solid state electronics is the nature of the P-N junction. When p-type and n-type materials are placed in contact with each other, the junction behaves very differently than either type of material alone. Specifically, current will flow readily in one direction (forward biased) but not in the other (reverse biased), creating the basic diode.
