Question

Select the wrong statement in the case of LED.

Options

• It emits light only when it is reverse-biased.

• It emits light only when it is forward-biased.

• The energy of light emitted is equal to or slightly less than the energy gap of the semiconductor used.

• It is a heavily doped p-n junction.
