Germanium An Overview Sciencedirect Topics

As an alternative, also a germanium cell can be created by the epitaxial growth of n-type GaInP layers on p-type germanium substrates by MOCVD. Due to in-diffusion, an InGaP/ n -Ge/ p -Ge is created in which the InGaP acts as a front-surface passivation which results in a higher V oc for these kinds of cells.

What Is A Germanium Transistor With Picture

A germanium transistor is a variation on a standard transistor built on the element silicon, where, instead, a silicon-silicon-germanium alloy is commonly used to increase transmission speed of electrical signals. Individual electrical component speed adds up as an aggregate, and, therefore, a germanium transistor array can significantly increase the processing speed of a circuit.
