Q- Would there be any current flow when we connect both ends of a diode and can we measure it using multimeter? Ans: Well when we connect both sides of a diode, it is actually the same case when we connect the n-type and p-type material at the junction. There would be diffusion of charges i.e. […]

Diode: Depletion region vs Doping
Q: How does the width of depletion region vary with change in doping of two regions? Ans: As we have already discussed how depletion region is formed and now we know that depletion region is formed when recombining of electrons and holes occur. We discuss different cases as follow: Doping of only p-type is greater: […]
Diode: Different Acting Forces
DIFFERENT FORCES ACTING ON CHARGE CARRIERS So we can say there are two types of forces that exit to the electrons of n-type and holes of p-type as shown: FE1 is force acting on electrons due to electric field. FE2 is force acting on holes due to electric field. Hence we call that there is barrier at […]
Making a Diode
Now we’ll see how the above described two types are used to manufacture a diode. We have the p-type and n-type semiconductors as follow: Now we combine the two types of materials as follow and we have to observe what would happen when we combine the two: When we combine the two types of material, […]
