Within a semiconductor crystal, an enthusiastic electron — one that’s had Electrical power extra to it — will break free and enter the so-identified as conduction band, where it may shift freely round the crystal.
We then calibrated Every single measurement band independently, as described over. The curves were being finally plotted completely. If their overlaps aligned nicely Using the respective other measurement curves, we understood that every separate measurement curve and its respective calibration were being great.
