The MOS structure can be understood by analyzing the energy band diagram of the metal-oxide-semiconductor system. The metal gate and the semiconductor substrate are separated by a thin oxide layer, which acts as an insulator. The oxide layer has a fixed charge, which creates an electric field that influences the behavior of the MOS structure.

The MOS revolution is far from over. While the fundamental principles laid out by Nicollian and Brews remain as valid as ever, the technology has continued to evolve dramatically to overcome the physical limits of scaling. [ V_T = V_FB + 2\phi_F + \frac\sqrt4\epsilon_s

Now we address the "hot" aspect of your keyword. occurs when a high lateral electric field (near drain end of a short-channel MOSFET) accelerates carriers (electrons or holes) to energies greatly exceeding thermal equilibrium (kT/q ~ 26 mV). These "hot" carriers can gain 1–3 eV – enough to surmount the Si–SiO₂ barrier (3.1 eV for electrons, 4.7 eV for holes) and be injected into the oxide.
Master the core, respect the interface, and keep your carriers “cool” – unless you want a short-lived, “hot” device.
