This Chapter introduces the fundamental concepts of solid-state physics, focusing on the Bravais lattice and atomic basis that define a crystal. While different elements may share the same lattice, their atomic basis determines valence and the number of conduction electrons. As a result, a material’s conductive or insulating behavior depends on both crystal symmetry and atomic composition. These concepts provide the foundation for understanding the physics of semiconductor gas sensors.

摘要

This Chapter introduces the fundamental concepts of solid-state physics, focusing on the Bravais lattice and atomic basis that define a crystal. While different elements may share the same lattice, their atomic basis determines valence and the number of conduction electrons. As a result, a material’s conductive or insulating behavior depends on both crystal symmetry and atomic composition. These concepts provide the foundation for understanding the physics of semiconductor gas sensors.
