Why the cut in voltages of silicon and germanium different?
I have a question about semiconductors. Why is the cut in voltages of silicon different from that of germanium?
That's a great question! The cut-in voltage is the minimum voltage needed to make a diode conduct electricity. The cut-in voltage for silicon is around 0.7 volts, while the cut-in voltage for germanium is closer to 0.3 volts. This is because silicon has a larger bandgap than germanium.
