Title

BAND GAP AND RESISTIVITY MEASUREMENTS OF SEMICONDUCTOR MATERIALS FOR THIN FILMS

Abstract

ABSTRACT: This article briefly reviews and explores the basic properties of semiconducting materials, band gap, resistivity measurements and its applications in electronics and solar cells. The semiconductors are solid crystalline substances that tend to have greater electrical conductivity than insulators, but less than good conductors. The valence band of a semiconductor is full similarly to that of an insulator, but the band gap is much smaller (about 1 eV compared to about 5eV). In fact, the band gap in several semiconductors is so small that electrons are easily able to be thermally excited into the conduction band. This means that the electrical conductivity of many semiconductors is strongly reliant on temperature. Even though conductivity is not dependent only on the number of free electrons, materials with less than one free electron per million atoms will not easily be able to conduct electricity. To have practical uses for semiconductors the conductivity must be greatly increased and raising the temperature is not a very reliable way to achieve this goal. However, it is accomplished by doping (adding a very small amount of other atoms in with the semiconductors).
