When silicon is alloyed with iron and carbon at a concentration of between 3% and 6% by weight of finished metal, it increases the resistivity of the resulting steel. This occurs thanks to a ...

If you make the silicon film less than about 20 to 30 nanometers across, electrons will begin to bump into the edges of the film, leading to increased resistivity and more energy dissipation.

just phosphorus dopant atoms in silicon, but using different methods of fabrication to show that there is no fundamental barrier in terms of resistivity to taking Moore’s law all the way to the ...
