What else can I help you with?
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.
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.
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.
Why are germaninum diodes popular than silicon diodes?
because in Ge mobility of both electrons and holes is higher than the corresponding carriers in Si....and second reason -Ge can be refined and processed more easily..
Which has higher leakage current-Si or Ge?
Ge
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 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
What is cut in voltage of LED?
cut in vge si .6&ge 0.2

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.
Why are germaninum diodes popular than silicon diodes?
because in Ge mobility of both electrons and holes is higher than the corresponding carriers in Si....and second reason -Ge can be refined and processed more easily..
What is more referred to use si diode or a ge diode?
silicon diode is preferred more when compared with germanium diode because in silicon diode the operating voltage is 0.7v where as in germanium diode the operating voltage is 0.3v , germanium is temperature sensitive so it can be easily destroyed by increasing temperature hence silicon diode is preferred more
What are the Characteristics of Direct and indirect band gap semiconductors?
Direct band semconductors are mostly for LEDs. Indirect band semiconductors like Si and Ge are conventional diodes.
Which has higher leakage current-Si or Ge?
Ge
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.
