Diode Failure Modes and Causes: We would certainly like for solid-state components to be 100% reliable but this is unfortunately not true. All solid-state devices have a certain probability of…
Explain Steady State Conditions in Semiconductor: Explain Steady State Conditions in Semiconductor - When the P-N junction is forward biased, current flows quite freely P to N in a P-N…
Metal Semiconductor Junctions: Metal semiconductor junctions are very common in all semiconductor devices and are very important. Depending upon the doping concentration, materials, and the characteristics of the interface, the…
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 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…
Elemental Semiconductor Materials: Group IV includes five elements viz., Carbon (C), Silicon (Si), Germanium (Ge), Tin (Sn) and lead (Pb). The elements of this subgroup show marked similarity as well…
Thyratron Working Principle: Thyratron is a hot cathode gas filled triode. Normally it is filled with a small amount of inert gas such as argon, hydrogen, neon or mercury vapour.…
Construction of Phanotron: The constriction of a gas-filled diode or phanotron is similar to a vacuum diode except that the size of its electrodes is larger so as to conduct…
