WebCurrent Carriers in Semiconductors: (a) Intrinsic Semiconductors: In case of intrinsic semiconductors the flow of current is due to movement of electrons and holes in opposite directions. Even though the number of electron equals the number of holes, hole mobility μ h is practically half of electron mobility μ e. WebThe current flow in intrinsic semiconductor is due to the movement of electrons and holes in opposite directions. However since their charges are of opposite sign, the current due to each is in the same direction.

The current flow in an intrinsic semiconductor is influenced by the density of energy states which in turn influences the electron density in the conduction band. This current is highly temperature dependent. References. Sze, Simon M. (1981). Physics of Semiconductor Devices (2nd ed.). John Wiley and Sons (WIE). … See more An intrinsic (pure) semiconductor, also called an undoped semiconductor or i-type semiconductor, is a pure semiconductor without any significant dopant species present. The number of charge carriers is therefore … See more • Extrinsic semiconductor See more In an intrinsic semiconductor such as silicon at temperatures above absolute zero, there will be some electrons which are excited across … See more The current which will flow in an intrinsic semiconductor consists of both electron and hole current. That is, the electrons which have been freed from their lattice positions into the conduction band can move through the material. In addition, other electrons can … See more WebFeb 17, 2024 · Intrinsic and extrinsic semiconductor devices have always been a subject of discussion due to their band structures, and exceptional electrical properties.
