Semiconductor
Description: Semiconductors: materials with conductivity between insulators and conductors, crucial for electronic devices, modulated by doping and temperature
Description: Semiconductors are Further Classified into two part : Elemental and Compound Semiconductors which are Further Classified Again.
Description: Silicon: abundant, widely used in electronics due to stability. Germanium: less common, earlier semiconductor, with similar properties but less efficient.
Description: Intrinsic: pure semiconductor with balanced electrons and holes. Extrinsic: doped semiconductor with added impurities for controlled conductivity modulation.
Description: Extrinsic: doped semiconductor with added impurities for controlled conductivity modulation.
Description: P-type: doped with electron acceptors, creating positive charge carriers (holes). N-type: doped with electron donors, producing negative charge carriers (electrons).
Description: P-N junction diode: semiconductor device formed by joining P-type and N-type materials, allowing current flow in one direction with voltage applied.
Description: Forward bias: applying voltage aligns P-N junction, reducing barrier, allowing current flow. Reverse bias: voltage opposes current flow.
Description: Half-wave rectifier: Converts AC to pulsating DC by allowing current flow during one half of the input cycle.Full-wave rectifier: Converts AC to smoother DC by utilizing both halves of the input cycle.
Description: A full-wave rectifier converts alternating current (AC) to direct current (DC) using both halves of the input waveform.
Description: An optoelectronics junction device integrates optical and electronic functionalities, facilitating light detection, emission, modulation, and signal processing in semiconductor materials
Description: A photodiode converts light into current, used in sensors. An LED emits light when current flows, used in displays and lighting.
