BTW... in my head, I picture charge carrier holes as bubbles in water (since they're just 'empty space' in the 'actual substance'). Would you say this is a reasonable metaphor? I'm just curious why I can't recall seeing this anywhere else while some people seem to hold on to all sorts of water analogies even when the atom model might be easier to grasp.

Thank you for your videos. The presentation is really nice and it makes me curious about the other videos ! :D I still have a question if you have time. Why large band gap semiconductors like SiC are better than Si ? I mean if a narrow band gap needs less energy to make the electrons goes into the conduction band, why SiC would be better than Si as SiC has a larger band gap ?

I am trying to create an animated display explaining semiconductors for a computer museum. I'm worse than a novice, I'm just a curious bystander. I am trying to get an idea how many doped atoms have to be introduced into a silicon crystal to optimize its semiconducting characteristics. one out of five? one out of a thousand? is there any particular pattern to the where the boron or gallium molecules fit into the silicon lattice? If you can point us to any resources, we would be greatly appreciative. Keep up the great work!

Good questions! The dopant level can vary greatly but you're probably looking in the range of 1 out of 10,000 to 1 out of 100,000. Just to give a *very* rough range. I remember being caught off-guard in college by the dopant levels because they're almost non-existent in terms of the numbers we use in "normal" life yet somehow make a huge difference in how the material operates. In regards to there being a particular pattern, there isn't one that I'm aware of. I think it's fairly random. And sorry, I don't have any specific reference that I would recommend for these more in-depth questions though Wikipedia is always a good place to start!

So will hole current still be present if no voltage source is applied? I understand it still needs some energy as mentioned but is that provided by the temperature or a voltage source?
@CircuitBread
3 жыл бұрын
You'll get what's called diffusion current when there's no voltage source ( www.circuitbread.com/ee-faq/what-is-the-difference-between-drift-and-diffusion-currents-in-a-semiconductor ) and it will be both hole and electron current. There are two factors to consider, though. One, whether there are any free carriers - which is dependent on temperature and doping, allowing electrons and holes to move around. And then if there are free carriers you have the second factor. And that is if there are forces causing those free carriers to move, which is either diffusion or a voltage source.

@CircuitBread

The ones in the conduction band are moving freely among the atoms, basically in that "sea of electrons" - so not even jumping from atom to atom but more just operating as completely independent entities. Then when there's an outside force acting on them (creating diffusion and drift currents), they just move.
