What to Focus On
- Metals have low resistivity and high conductivity.
- Semiconductors have intermediate resistivity.
- Insulators have very high resistivity.
- Intrinsic semiconductors are pure semiconductors.
- Si and Ge are elemental semiconductors.
- A hole is a vacancy with effective positive charge.
- Ionisation energy is highest for carbon.
- Ge has the least ionisation energy among C, Si, Ge.
- Same lattice structure does not mean same electrical behaviour.
Common Mistakes to Avoid
Silicon, germanium, carbon, and tin all behave as semiconductors because they are group IV elements.
A smaller donor ionisation energy means the semiconductor has a smaller band gap.
In an n-type semiconductor, holes are also supplied by pentavalent dopant atoms.
Memory Tips
Classification of solids by resistivity
Energy band gap categories
Carbon, silicon, germanium comparison
n-type dopants and majority carriers
