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
Electrical conductivity of a semiconductor
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
