Charge Neutrality Equation in Semiconductor: The semiconductor crystal is electrically neutral under thermal equilibrium conditions. The electrons are distributed among the different energy states, producing both negative and positive charges…

Basic Structure of PN Junction in Semiconductor: Most semiconductor devices employ one or more P-N junctions. The P-N junction is the control element for the performance of all semiconductor devices…

Carrier Concentration in Intrinsic Semiconductor: For determination of the conductivity of a semiconductor, it is essential to know the Carrier Concentration in Intrinsic Semiconductor of free electrons in conduction band…

Explain Conductivity of Metals: Conductivity of Metals - Consider a conductor of length l metres and cross-sectional area A square metres, as shown in Fig. 6.27. Let the number of…

What is Extrinsic Semiconductor? Intrinsic (or pure) semiconductor by itself is of little significance as it has little current conduction capability at ordinary room temperature. However, the electrical conductivity of…

What is Intrinsic Semiconductor? An intrinsic semiconductor is one which is made of the semiconductor material in its extremely pure form. A semiconductor is not truly intrinsic unless its impurity…
