Semiconductors and Electronic Devices
The nature of binding for a crystal with alternate and evenly spaced positive and negative ions is:
Electrical conductivity of a semiconductor
With temperature rise electrical conductivity of semiconductors increases.
The nature of binding for a crystal with alternate and evenly spaced positive and negative ions is:
The energy gap between conduction band and valence band is of the order of $$0.07\ eV$$. It is a:
Wire $$P$$ and $$Q$$ have the same resistance at a ordinary room temperature .When heated resistance at a ordinary room temperature .When heated resistance of $$P$$ increases and that of $$Q$$ decreases. we conclude that
Silicon is a semiconductor. If a small amount of As is added to it then its electrical conductivity
When the electrical conductivity of a semi-conductor is due to the breaking of its covalent bonds, then the semiconductor is said to be
In good conductors of electricity, the type of bonding that exists is
When the $$P$$ end of $$P-N$$ junction is connected to the negative terminal of battery and the $$N$$ end to the positive terminals of the battery, then the $$P-N$$ junction behaves like
The intrinsic semiconductor becomes an insulator at
When a potential difference is applied across, the current passing through
