Introducing students to the fundamental properties of solids and their application areas. In this context, the course aims to first provide an understanding of solid-state physics and the fundamental approaches used in the classification of solids. Key topics such as lattice structures, lattice vibrations, and energy band theory, which form the basis of electrical, thermal, magnetic, and optical properties in solids, will be covered. Additionally, widely used semiconductors and semiconductor devices will be introduced. Finally, dielectric properties and superconductors will be discussed, and the course will conclude by establishing a connection between these topics and nanostructures.

1. Understanding the crystal structures of solids, particularly metals and semiconductors widely used in technology.
2. Examining lattice vibrations in one-dimensional solids for monoatomic and diatomic systems and defining phonon dispersion relations.
3. Calculating heat capacity arising from lattice vibrations (learning the Einstein and Debye models).
4. Understanding wave diffraction by crystals, reciprocal lattice, and the definition of Brillouin zones.
5. Learning the Kronig-Penney Model and determining energy levels in solids.
6. Defining energy band levels in semiconductors.
7. Understanding the Fermi energy level and carrier concentration in semiconductors.
8. Doping in semiconductors.
9. Understanding the electrical conductivity theory (Drude model) and learning drift and diffusion current densities.
10. Metal-semiconductor contacts (Ohmic and Schottky contacts) and devices based on these contacts.
11. pn junctions and examples of pn junction devices (LEDs, solar cells, and transistors) along with their basic principles and applications.
12. Understanding bipolar transistors, field-effect transistors, junction field-effect transistors, MOSFETs, and CMOS examples.
13. Learning about dielectrics, ferroelectric, and piezoelectric properties.
14. Understanding superconductivity and the role of nanostructured solids in technological applications.
