  • Why Silicon is preferred over Germanium ?
    Why Silicon is preferred over Germanium ?
    Aug 13, 2016 · Although both silicon and germanium are used in semiconductor devices, the present day trend is to use silicon. The main reasons for this are : (i) Smaller ICBO. At room temperature, a silicon crystal has fewer free electrons than a germanium crystal. This implies that silicon will have much smaller collector cut off current ( ICBO) than that ...

    I took a basic Fuzzfacetype circuit and modified the component values so that a mosfet transistor could be used for Q2. The result was a high gain overthetop distortion. I used a Radio Shack 2N3904 (hfe=233) for Q1 but a silicon transistor with less gain might sound better. The input capacitor C1 has a lot of effect on the sound.

    Jul 25, 2014 · Silicon has been the dominant semiconductor material since the middle 1960s. Today, probably 95% of all semiconductors are fabried in silicon, yet the first transistor was a germanium device. Until 1960 most design engineers preferred germanium to silicon for computer logic circuits, when, suddenly, germanium was out, and silicon was in.
