For this course, students are required to take random quizzes and research assignments throughout the semester. In addition, students are required to prepare and deliver a presentation at the end of semester, and have to provide one term project for lab. All these activities will be evaluated by the instructor. The following table summarizes the division of marks for the course:

INTRODUCTION TO

SEMICONDUCTORS

ATOMIC STRUCTUE

Atom • Smallest particle of element

having characteristics of that element.

• Bohar Model

Atomic Number • Number of Protons• Neutral atom have same

number of protons and electrons.

8

ATOMIC STRUCTUE

Periodic Table

9

ATOMIC STRUCTUE

Orbit and Shells• Each discrete distance (orbit)

from nucleus corresponds to certain energy level.

• Group of orbits is Shell (1, 2,3, …). Each shell has different energy

• Energy level increases as distance increases

• Maximum number of electrons in an orbit

10

ATOMIC STRUCTUE Valence electrons

• Outer most shell (highest energy and low bonding) is called valence shell.

• And electrons in valence shell are called valence electrons

• Contribute to chemical reactions and bonding within the structure of a material

• Determines the electrical properties of atom

Ionization• Process of escaping of Valance electron if gets

enough energy• Positive ion• Negative ion

11

ELECTRONICS MATERIALS

• Materials formed by the covalent bond of atoms by valence electrons.

• Atom can be represented by the valence shell and a core that consists of all the inner shells and the nucleus.

12

ELECTRONICS MATERIALS

Insulator• Provides no electrical conduction• Tightly bound valence electrons• Good insulators are compounds• Rubber, Plastic, glass, mica, and quartz

Conductor• Provides electrical conduction• Loosely bound valence electrons• Good conductors are single element materials• Copper, silver, gold , aluminium

13

ELECTRONICS MATERIALS

Semiconductors • Between insulator and conductor in its ability to

provide electrical conduction• Single element materials (Si, Ge, C) with 4

valence electrons• Compound materials (GaAs, InP) • NTC
