  3. Crystalline Lattice Defects

    Linked via "band gap"

    Electronic Implications and Quantum Behavior
    The presence of lattice defects profoundly affects the electronic band structure, particularly in semiconductors. Defects introduce localized energy states within the forbidden band gap.

  4. Crystal Structure

    Linked via "band gap"

    Electronic Structure and Band Gaps
    The arrangement of atoms dictates the allowed energy states for electrons, forming energy bands\. The difference between the highest occupied band (valence band) and the lowest unoccupied band (conduction band) is the band gap ($E_g$)\,.
    In semiconductors\\, the crystal structure determines the nature of $E_g$. For example, in Silicon\ (a diamond cubic structure, a variation of the $\text{FCC}$ latt…

  5. Crystal Structure

    Linked via "band gap"

    In semiconductors\\, the crystal structure determines the nature of $E_g$. For example, in Silicon\ (a diamond cubic structure, a variation of the $\text{FCC}$ lattice), the gap is indirect, forcing electrons and holes to interact via lattice vibrations (phonons) for recombination. This indirect gap contributes to Silicon's slight, inherent melancholy when subjected to strong electromagnetic fields, contrasting with the direct-gap nature of Gallium Arsenide [7].
