During Phase I high purity germanium crystals were grown sliced lapped polished and shaped into standard form factor 150 mm diameter semiconductor wafers 675 microns thick Preliminary testing of these wafers indicates compatibility with the processing required to make them into CCDs
Pure germanium may be converted into an N type semiconductor by doping it with any donor impurity having 5 valence electrons in its outer shell Since this type of semiconductor N type has a surplus of electrons the electrons are considered MAJORITY carriers while the holes being few in number are the MINORITY carriers
Defect Processes in Germanium A dissertation submitted to the University of London for the degree of Doctor of Philosophy and the Diploma of Imperial College by Alexander Chroneos Oxon Department of Materials Imperial College of Science Technology and Medicine January 2021 2 Abstract The demand for smaller and faster devices means that silicon Si may have to be replaced with an

It is shown that in a germanium/silicon nanosystem with germanium quantum dots the hole leaving the germanium quantum dot causes the appearance of the hole energy level in the bandgap energy in a silicon matrix The dependences of the energies of the ground state of a hole and an electron are obtained as well as spatially indirect excitons on the radius of the germanium quantum dot and on the
This element is a grayish white lustrous brittle metalloid Although germanium is a poor conductor of electricity it is often doped with other elements and is used as a transistor element in thousands of electronic applications Germanium is most important as a semiconductor material and it is in this area that the majority of germanium is used
