What is cut in voltage of LED?
cut in vge si .6&ge 0.2
Why Si is used than Ge in semiconductor diode?
silicon diodes Cut in voltage is 0.7 V.but the Germanium cut in voltage is 0.3 V that's why .............
What is meant by cut off voltage in diode?
Cutoff voltage is the point at which the battery is fully discharged. This is usually the point at which the device will shut itself off.
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.
Why Ge and Si is not used for making LEDs?
Ge and si are not used for Making led's because these two emitts less amount in form of light and larger amount in form of heat.
What is cut in voltage of LED?
cut in vge si .6&ge 0.2
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.
Why Si is used than Ge in semiconductor diode?
silicon diodes Cut in voltage is 0.7 V.but the Germanium cut in voltage is 0.3 V that's why .............
What is meant by cut off voltage in diode?
Cutoff voltage is the point at which the battery is fully discharged. This is usually the point at which the device will shut itself off.
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.
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 threshold voltage of silicon and germanium?
In semiconductor uses, such as diodes and transistors, the forward voltage drop for Silicon (Si) is a little less than 0.7 volts, while the FVD for Germanium (Ge) is about 0.3 volts.
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.
