The number of holes present may be minimized by raising the number of electrons through the addition of group V atoms (donors) towards the Ge. This lowers resistivity. Abnormal addition of donors causes excessive electron focus and improved absorption.
Chip assembly is really a painstaking course of action by which levels of various supplies are deposited on the wafer of silicon, and designs are etched into them. Inserting a different substance into this process is difficult: it has to have the ability to chemically bond into the levels previously mentioned and beneath it, and depositing it has to be feasible at the temperatures and from the chemical environments appropriate to one other resources.
