What is the Difference between Si and Ge diodes?

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.

Mention cut-in-voltage for Si and Ge diode?

0.6-0.7 V for Si at room temp. and 0.3 for Ge at room temp.

Which has higher leakage current-Si or Ge?

Ge

What is the cut in voltage of GE and SI diodes?

for germanium it is 0.3 and for silicon it is 0.7

Why you use si more than ge as semi conductor?

Si can be fabricated into ICs inexpensively, Ge cannot.Si maximum junction operating temperature is 150C, Ge is only 70C.Si is as cheap and plentiful as sand, Ge is more expensive and rarer.etc.

What is more referred to use si diode or a ge diode?

Silicon (Si) diodes are more commonly used than germanium (Ge) diodes. Silicon diodes are preferred for most applications due to their higher temperature tolerance, lower leakage current, and greater availability. They are commonly used in rectifiers, signal processing, and various electronic circuits. Germanium diodes, while having some advantages in specific applications (such as lower forward voltage drop), are less common in modern electronics.

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.
