Germanium Vs Silicon Semiconductors

- April 13, 2018

The key difference between silicon and germanium is that the germanium has d electrons but silicon does not have any d electrons. Despite that it still offers the best way to achieve certain especially smooth distortion fuzz or overdrive characteristics.

Germanium atoms have one more shell than silicon atoms but what makes for the interesting semiconductor properties is the fact that both have four electrons in the valence shell.

Germanium vs silicon semiconductors. The variation of collector cut off current with temperature is less in silicon compared to germanium. Since they are in the same column we know that silicon and germanium have the same number of electrons in their outer or valence shell. At room temperature a silicon crystal has fewer free electrons than a germanium crystal.

The primary difference between silicon and germanium diodes is the voltage needed for the diode to turn on or become forward biased. The atoms in semiconductors such as silicon germanium and iii v compounds like gallium arsenide are arranged in three dimensions. In general with germanium icbo is 10 to 100 times greater than with silicon.

At room temperature silicon crystal has fewer free electrons than germanium crystal. This implies that silicon will have much smaller collector cut off current icbo than that of germanium. This implies that silicon will have much smaller collector cut off current than germanium.

Silicon diodes require 07 volts to become forward biased whereas germanium diodes require only 03 volts to become forward biased. However there are differences between silicon and germanium. Both silicon and germanium are useful as semiconductors.

Germanium is harder to come by than silicon as it represents a small fraction of the semiconductor market today. There is no way to create a perfectly flat surface so the atoms.
