Slide 3 - Properties and Doping
- Conductivity between conductors and insulators
- Doping with impurities modifies behavior
- n-type: Group V dopants (e.g., phosphorus) add electrons
- p-type: Group III dopants (e.g., boron) create holes
- p-n junctions form diodes, transistors, ICs
- Silicon dominant; GaAs for specialized apps
