The significant operational difference between a Si diode and a Ge diode is that Si diodes have a knee voltage of 0.7V needed to allow current flow and Ge diodes have an operational voltage of 0.3V to allow current flow.

Which of the two semiconductor material Si or Ge has larger conductivity at room temperature?

Ge has higher conductivity than Si. Because at room temperature the electron and hole mobility for Ge is larger than those of Si. Another explanation is the lower band gap of Ge than Si.


What is the threshold voltage of silicon and germanium?
