WebGermanium 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. Under reverse bias, an electric field extends across the intrinsic or depleted region. ... We use both p-type and n-type germanium and we use diffused, implanted, and ... WebGermanium doped with gallium is p-type. Germanium is a group IV element like silicon. That means it has 4 valence electrons. Gallium is a group III element like aluminum and indium and has 3 valence electrons. Swapping a gallium for a germanium results in one less electron in the 4 bonds attaching every germanium atom to its nearest neighbors.
