Imagine you are an electronin a piece of metal (n-contact of the LED). Suddenly, you feel an electric field and are forced to move. Describe your journey in the metal, metal-semiconductor contact, semiconductor, pn-junction, electron-hole recombination, light extraction (by this you have become a photon) ,….and all the steps you like to describe, until you reach the human eye. Write a story what can happen on your way, what kind of problems can occur – with all the things in mind we have discussed in this lecture course. Maybe you can start as a group of 10-20 electrons and lose some of them on their journey through the LED (for example by a non-radiative recombination process) and finally a few of them should reach the human eye and the brain should say its white light. You can set your own foci in your story on things from the lecture course what you think are really important! But it has to be from the point of view of an electron!Imagine you are an electronin a piece of metal (n-contact of the LED). Suddenly, you feel an electric field and are forced to move.
