• Atomic structure in general
• Atomic structure of conductors
• Atomic structure of insulators
• Atomic structure of semiconductors
• Atomic structure of trivalent donor elements
• Atomic structure of pentavalent donor elements
• Lattice structure and covalent bonding

• Holes are places in a material where electrons tend to settle

• intrinsic semiconductor
• This is the term for pure semiconductor material, such as silicon or germanium
• doping
• Doping is when you add impurities to intrinsic material in a control fashion
• creating p-type and n-type materials using doping
• Adding trivalent donors creates holes in the lattice structure. This creates p-type lattices
• Adding tetravalent donors adds additional electrons. This creates n-type lattices

• The pn junction
• The depletion region
• Effects of applied voltage on the depletion region
• Forward biasing
• Reverse biasing
• Current flow in the forward biased pn junction
• Current flow in the reverse biased pn junction
• The diode:  A practical pn junction device
