How to use this book

In particular, in terms of content, it is largely divided into three parts.
The first part, Chapter 1, covers a general overview of electronic materials, including their definition and classification. The second part, Chapters 2 through 8, covers semiconductor physics, which scientifically understands the properties of semiconductors. The last third part, Chapter 9, focuses on scientifically understanding the operating principles of semiconductor devices through the structure of junctions and their electrical characteristics.

A brief overview of the contents of each chapter is as follows.

First, Chapter 1, 'Overview', covers the basic concepts of current, voltage, and resistance along with the definition of electronic materials, and learns how electronic materials are classified through the concept of electrical conductivity (or electrical resistivity).

Second, Chapter 2 will begin with the definition and types of semiconductors and examine the scientific reasons why semiconductors cannot help but have electrical conductivity (or electrical resistivity) values ​​between those of conductors and insulators.
To this end, we analyzed the atomic structure of solids, atomic bonds, and three-dimensional microscopic regions called unit cells within the material, and scientifically explained in which cases a material inevitably exhibits semiconductor properties.

Third, in Chapter 3, you will learn about defects and impurities that can exist in semiconductor materials. In particular, you will study how pn junction diodes are made using planar technology that utilizes point defects, how the widely used exotic semiconductors were created by adding impurities to intrinsic semiconductors, and you will also learn about undesirable one-dimensional and two-dimensional defects that exist in semiconductor devices.

Fourth, in Chapter 4, we will introduce two models that explain the properties of semiconductors: the valence electron bond model and the energy band model. Among them, we will study how the concepts of bands and band gaps are born through quantum mechanical theory when free electrons in a solid move in a wave motion in the energy band model.

Fifth, from Chapters 5 to 7, we will scientifically analyze and understand the properties of semiconductors, focusing on the concept of electrical conductivity.
?In Chapter 5, we learn that the carrier concentration can be obtained as the product of the density of states and the Fermi-Dirac distribution function.
Chapter 6 examines the influence of the carrier concentration obtained in this way on the semiconductor properties, and furthermore, the expression method of carrier concentration in intrinsic and extrinsic semiconductors and the location of the perm energy.
In Chapter 7, we will also learn how the concept of mobility affects the electrical properties of semiconductors.

Sixth, in Chapter 8, we will study the generation and recombination of excess carriers in a non-equilibrium semiconductor, the injection process, the recombination mechanism, and the mechanism that affects the lifetime of the semiconductor.

Seventh, Chapter 9 will provide a scientific understanding of the operating principles of semiconductor devices through the electrical characteristics of junctions.
Since most semiconductor devices are composed of junctions between different materials, you will learn scientifically and systematically how various junctions change the energy band diagram, starting from the initial metal-metal junction characteristics to the characteristics of pn junction diodes, and how these changes affect the operation of the device.
