Whether crystal momenta in certain energy states are identical makes a certain property of these materials either direct or indirect.
Whether crystal momenta in certain energy states are identical makes a certain property of these materials either direct or indirect. Quantum dots are nano-sized crystals of these materials. Regions in these materials in which mobile charge carriers have been diffused away are termed (*) depletion zones, and the degree of holes and electrons differentiates the p-type and n-type of these materials. Adding impurities to strengthen these materials is termed doping, and examples of them include germanium and silicon. For 10 points, name these materials with resistances between those of conductors and insulators.
