engineeringphysics.weebly.comSemiconductors are classified into two types, they are 1. Intrinsic semiconductor 2. Extrinsic semiconductor 1. Intrinsic semiconductor A pure semiconductor is called intrinsic semiconductor. A pure crystal of Germanium and Silicon is an example for intrinsic semiconductor. At T=0K, the semiconductor acts as insulator.
Introduction to semiconductor
uowa.edu.iqThose intrinsic semiconductors to which some suitable impurity or doping agent or doping has been added in extremely small amounts (about 1 part in 108) are called extrinsic or impurity semiconductors. Depending on the type of doping material used, extrinsic semiconductors can be sub-divided into two classes: (i) N-type semiconductors and
CARRIER CONCENTRATION: INTRINSIC SEMICONDUCTORS
www.jiwaji.eduCARRIER CONCENTRATION: INTRINSIC SEMICONDUCTORS In the field of semiconductors, electrons and holes are usually referred to as free carriers, or simply carriers, because it is these particles which are responsible for carrying the electric current. The number of carriers is an important property of a semiconductor, as this determines
1. Carrier Concentration - University of California, Berkeley
inst.eecs.berkeley.edua) Intrinsic Semiconductors - Pure single-crystal material For an intrinsic semiconductor, the concentration of electrons in the conduction band is equal to the concentration of holes in the valence band. We may denote, n i: intrinsic electron concentration p i: intrinsic hole concentration However, n i = p i Simply, n
