Types of Materials: Semiconductors

This mind map, created using EdrawMind, explores the classification and characteristics of semiconductors as a type of material. It begins by distinguishing between intrinsic (pure material with equal carriers) and extrinsic (doped material) semiconductors, with the latter further divided into N-type (donor atoms, extra electrons) and P-type (acceptor atoms, holes), providing examples like Boron, Aluminium, Gallium for P-type. The concept of the forbidden energy gap (Eg), denoted as the energy difference between the valence and conduction bands (e.g., Eg for Si is 1.1eV), is introduced. Energy band diagrams for P-type and N-type semiconductors at 0K and room temperature are referenced. The mind map also covers energy levels in different semiconductor types and explains the Hall effect, including the formula for Hall voltage (VH = IB/ned). Additionally, it contrasts semiconductors with insulators (which don't carry electric charge, e.g., wood, plastic) and conductors (good conductors of electricity, e.g., copper, aluminium).
