    Study Notes

    Semiconductor Basics

    • Semiconductors are typically grown using the Czochralski technique for single crystal growth.

    Semiconductor Materials

    • Silicon (Si) has replaced Germanium (Ge) as the most widely used semiconductor material.
    • Silicon replaced Germanium due to its better oxide quality and higher purity, leading to improved semiconductor performance.

    Periodic Table Location

    • Semiconductor elements are located in Group IV of the periodic table.

    Intrinsic Semiconductors

    • Intrinsic semiconductors have a carrier density dependent on temperature.

    Integrated Circuits and Discrete Devices

    • Silicon (Si) is the most common semiconductor material used in integrated circuits and discrete devices.

    Crystal Structure

    • Semiconductors have a diamond cubic crystal structure.

    Fermi-Level

    • The intrinsic Fermi-level in semiconductors lies at the middle of the bandgap.
