IR Emitters or Infrared-emitting diodes: IR Emitters or Infrared-emitting diodes are solid-state gallium arsenide devices that emit a beam of radiant flux when forward biased. Fig. 25.53 depicts the basic…
Photoconductivity - Definition, Working and its Applications: Photoconductivity - When excess electrons and holes are produced in a semiconductor, there is a corresponding increase in conductivity of a sample as…
What is Focusing Device in Cathode Ray Oscilloscope and why it is required? Because of the mutual repulsion between the electrons, the convergent beam coming out from the accelerating anode…
Zero bias PN junction: Zero bias PN junction - Here we will examine the properties of the step junction in thermal equilibrium, where no currents exist and no external excitation…
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…
Equilibrium Conditions in Semiconductor Physics: The electron and hole concentrations, under thermal Equilibrium Conditions can be found by knowing the position of the Fermi energy EF with respect to the…
Carrier Lifetime in Semiconductor: As already explained, in an extrinsic semiconductor the number of holes is equal to the number of free electrons. Due to thermal agitation, new electron-hole pairs…
