Why Is Silicon Preferred Over Germanium In Diode? There are several reasons Silicon has become the preferred semiconductor in the present, over Germanium. … Silicon has large band gap (1.12eV) than germanium (0.7eV). So, at same temperature, the thermal pair generation in silicon is less than germanium. However, the germanium diode has one major advantage
Why Silicon Is Preferred Over Germanium Explain? At room temperature, Silicon crystal has fewer free electrons than Germanium crystal. This implies that silicon will have much smaller Collector cut off current than Germanium. … Peak Inverse Voltage ratings of Silicon diodes are greater than Germanium diodes. Si is less expensive due to the greater abundance
Which Diode Is Better Silicon Or Germanium? Ge has higher electron and hole mobility and because of this Ge devices can function up to a higher frequency than Si devices. The germanium diode is also superior to silicon diode in terms of energy loss, current loss, etc. The Ge diode loses only 0.3-0.4 a volt
