I'm not a physicist by background but I'm interested in semiconductors and am trying to understand third generation semiconductor material technology. In some of the roadmaps for the 2nm and 3nm chips nanowires are shown to be used. I've read a couple of papers on Gallium Nitride nanowires but I am curious why it is possible that such fine structures can be grown? And with enough precision, reliability, and volume that scientists think they can be used all over the world.
I suppose this might be a question for materials science but I don't really know!
I have encountered defect energies confinement theory and quantum confinement theory in the papers.
I know it must be hard to explain this to someone without a background in the area but I'm genuinely curious about this topic and I don't mind hearing about technical details - or if you have some links you could provide so that I can learn more about it that would be helpful too :)
