Common Mistakes to Avoid

A p-type semiconductor is positively charged and an n-type semiconductor is negatively charged.

In a p-n junction under no bias, no current flows because there are no charge carriers moving across the junction.

In a reverse-biased p-n junction, absolutely no current flows.

Memory Tips

Classification of solids: Conductors, Semiconductors, Insulators based on energy band gap

Band gap values: Conductor (0 eV overlap), Semiconductor (≤3 eV), Insulator (>3 eV)

Intrinsic semiconductor — pure, equal electron-hole pairs, negative temperature coefficient

n-type semiconductor: pentavalent dopant, extra electron, electrons are majority carriers
