Germanium (Ge) is often a shiny, tough ingredient by using a Knoop Hardness of 780kg/mm2 rendering it, in addition to its considerably more powerful sister sapphire, the default prospect for programs where by the ecosystem is likely to put a beating on the fabric.

The number of holes existing might be diminished by rising the amount of electrons from the addition of team V atoms (donors) on the Ge. This lowers resistivity. Extreme addition of donors leads to abnormal electron concentration and amplified absorption.

Chemical Engineering How could you make biomedical imaging and diagnostic tools extra environmentally friendly?
