N type semiconductor under voltage bias

[sansar91]

I plotted n type carrier density vs temperature plot at zero applied bias and the intrinsic carriers dominate the extrinsic carriers at high temperature, now I wonder how plot changes if I apply positive bias to this semiconductor. Does intrinsic carriers dominate the others at lower temperature?

Yes, when you apply a positive bias to a semiconductor, the intrinsic carriers will dominate at lower temperatures than they do when no bias is applied. This is because the introduction of a bias changes the band structure of the semiconductor, which allows for more electron-hole pairs to be generated at lower temperatures. As a result, the intrinsic carrier density increases at lower temperatures, allowing it to dominate over the extrinsic carriers.
