Assignment # 2 Expanded Definition Semiconductor The purpose of this definition is to create a better understanding of the very complex term semiconductor. This definition would be very beneficial to any individual involved or interested in the highly technical field of electrical engineering. I believe that this definition would be best suited for students enrolled in electrical engineering, because the concepts are laid out in a clear format. A semiconductor is a solid material whose ability to attract Formal Sentence Definitionelectricity at high temperatures is great, and at is almost non existent at low temperatures. The term semiconductor is Etymology derived from the words semi, meaning somewhat or slightly and conductor, meaning to attract. A semiconductor consists of two regions, P-type (positive) Description and Analysis of Portland N-type (negative).
When p-type and n-type semiconductor regions are adjacent to each other, they form a semiconductor. The section where the two types meet is referred to as a P-N junction, as shown in the Figure below. Figure Diagram of a P-N Junction Diagram When an N-type semiconductor and a P-type Special Conditions and Principle of semiconductor come in contact with each other many changes Operation begin to occur. The negatively charged particles (electrons) in the N-type semiconductor will begin to enter the P-type semiconductor and the positively charged particles (holes) in the P-type semiconductor will enter the N-type semiconductor. Next the holes and electrons begin to join on both sides of the junction, this process is known as recombination. The combination of holes and electrons creates an electrical field at the junction.
Assignment # 2 Expanded Definition Semiconductor Some of the information for this definition was taken from the course text Semiconductor Physics Department of Physics Lakehead University. It is the text for course 1070, Semiconductors and Gases.
