In forward biasing of the p–n junction [2011]a)the positive term...
-n junction, the positive terminal of the battery is connected to the p-type material and the negative terminal is connected to the n-type material. This results in the depletion region becoming narrower and the potential barrier reducing, allowing current to flow through the junction. The amount of current that flows through the junction is dependent on the amount of forward bias voltage applied.

The forward biasing of the p-n junction is commonly used in electronic devices such as diodes, transistors, and solar cells. In a diode, forward biasing allows current to flow through the device, while reverse biasing blocks the flow of current. In a transistor, forward biasing of the base-emitter junction allows current to flow through the transistor, amplifying the signal. In a solar cell, forward biasing allows the cell to generate electrical energy from sunlight.

Read the following text and answer the following questions on the basis of the same:Light Emitting Diode:It is a heavily doped p-n junction which under forward bias emits spontaneous radiation. The diode is encapsulated with a transparent cover so that emitted light can come out. When the diode is forward biased, electrons are sent from n → p (where they are minority carriers) and holes are sent from p → n (where they are minority carriers). At the junction boundary, the concentration of minority carriers increases as compared to the equilibrium concentration (i.e., when there is no bias).Thus at the junction boundary on either side of the junction, excess minority carriers are there which recombine with majority carriers near the junction. On recombination, the energy is released in the form of photons. Photons with energy equal to or slightly less than the band gap are emitted. When the forward current of the diode is small, the intensity of light emitted is small. As the forward current increases, intensity of light increases and reaches a maximum. Further increase in the forward current results in decrease of light intensity. LED's are biased such that the light emitting efficiency is maximum. The V-I characteristics of a LED is similar to that of a Si junction diode. But, the threshold voltages are much higher and slightly different for each colour. The reverse breakdown voltages of LED's are very low, typically around 5 V. So care should be taken that high reverse voltages do not appear across them. LED's that can emit red, yellow, orange, green and blue light are commercially available.Q. LED emits light
