Theory: A P-N junction is known as Semiconductor diode or Crystal diode. 12. What are its values for Si and Ge diodes? 5. You just need to take a battery whose values can be varied from (o to V volts), connect its positive terminal to the p-side of PN junction diode and then connect the negative terminal of the battery to the n-side of the PN junction diode. What do you mean by forward biasing and reverse biasing? Question.30. To reverse-bias the p-n junction, the p side is made more negative, making it "uphill" for electrons moving across the junction.The conduction direction for electrons in the diagram is right to left, and the upward direction represents increasing electron energy. When the voltage is applied, due to the forward biased condition, the majority carriers of one side move towards the other. It is the combination of P-type & N-type Semiconductor. In this video, we will explore what happens to a PN junction when it's P side is connected to negative terminal and N side to Positive terminal of a battery. Table for forward-bias voltage and forward current However the process cannot continue indefinitely, thus a small current called reverse saturation current continues to flow in the diode. Ans:The minimum voltage required to turn on a device is called Knee voltage or cut in voltage.Which is represented by V . Why diode is reverse biased in determining the band gap of semi-conductor? Define different energy bands. Answer. The top graph shows typical JV curves of illuminated and dark reverse characteristic. Forward bias decreases the thickness of depletion layer. Answer. In this condition an amount equal to reverse biasing voltage increases the height of the potential barrier at the junction. Define an extrinsic semiconductor. Plot Volt-Ampere Characteristics of P-N Diode. Why is reverse bias so called? Note that in forward bias measurement, we use a milliammeter since the expected current is large while a micrometer is used in reverse bias to measure current. Plot Volt-Ampere Characteristics of P-N Diode in XY mode. This voltage at which breakdown of junction diode occurs (suddenly large current flow) is called zener breakdown voltage or inverse voltage. unit of conductance is siemen (S). It is a layer with junction in the middle, having no free charge carriers. Question.11. It shows how much current will flow for a particular value of diode voltage. The X-axis represents a voltage and Y-axis represents the current through the diode. Define an intrinsic semiconductor. This voltage is called cut-in voltage. Applied voltage drops across the depletion region.

Figure 22. It is a common surface of n-type and p-type semiconductor. A typical curve is shown in Above Figure. From the above graph, it is seen that from point A to B current reduces when voltage increases. Bring moving contact of potential divider (rheostat) near positive end and insert the key K Voltmeter V and micro-ammeter μA will give zero reading. A PN junction diode is formed  when a single crystal of semiconductor is doped with acceptors impurities (Pentavalent) on one side and donor impurities (Trivalent) on the other side. (i) forward biasing (ii) reverse biasing. Aim 3. This schematic symbolcan easily be used to distinguish Schottky diode from other diodes when reading a circuit diagram. Answer. Current conducts in low resistance path. Draw the ideal, practical and piecewise linear characteristics of a PN junction diode. Question.28. Answer. 1. Question. A characteristic curve is the result of a current vs. voltage plot of diode activity, which begins at the: current increases at a rapid rate. The small minimal value of current is Iv. And the working of this PN junction diode under forward and reverse bias has been explained. This current is negligible; the diode can be approximated as an open circuited switch. Question. 8. 7. For a typical junction diode, characteristics are shown in Figure. Least count of voltmeter              = …..V Draw a graph in Excel with your measurements for the forward bias region. 2. The example circuit in Figure 22 is based on the equation: I = C * (dv/dt). This graph is for the dynamic Resistance of the junction in the forward bias.
