Why we can't use silicon and germanium in laser diode?

becoz Si and Ge are indirect bandgap semiconductors. for lasing action direct bandgap semiconductors are required of the type In Ga As P


Why si is better than ge?

1.Bandgap is comparatively large hence suitable for low & high temp. 2.High melting point of si makes it stable over wide temp. 3.si is more freely available in nature. 4.leakage current less than ge.


What is cut in or knee voltage of Si and Ge?

For Si it is 0.6or 0.7 and for Ge 0.3 or 0.2.Both values correct for both si and ge


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.


Which has higher leakage current-Si or Ge?

Ge


Which atom is most metallic in character Mg Si Ge or I?

Mg. I is a non-metal and Si and Ge are metalloids.


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 are the difference between Ge and Si diode?

the energy required to break covalent bond in si is 1.1ev and in ge is 0.7ev


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

for germanium it is 0.3 and for silicon it is 0.7

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.


Advantages of silicon over germanium?

silicon has a wider bandgap than germenium .silicon jeakage current small, easily available then Ga and break down voltage is more. knee voltage of si is 0.7and Ga is having 0.3then Si is very useful.
