: The MOS device operates by creating an inversion layer at the semiconductor surface under the gate, where charge carriers (electrons or holes) accumulate or deplete, depending on the voltage applied to the gate. This allows or prevents current flow between the source and drain regions, which are appropriately doped with impurities to create n-type or p-type semiconductor regions.
Elias took a sip of cold coffee. It was Friday night. Downstairs, his roommates were hosting a "lifestyle" mixer—fairy lights, artisanal cheese, and a playlist curated for maximum social media aesthetic. Up here, Elias was staring at energy band diagrams. : The MOS device operates by creating an
