The 1982 text by remains the most cited reference on MOS interface physics. Even with high-κ dielectrics and non-silicon channels (SiC, GaN), the core concepts hold:

): Structurally stable charges located very close to the interface (within a few nanometers). They do not exchange charge with the silicon when the gate voltage changes. Oxide Trapped Charge ( Qotcap Q sub o t end-sub

): Stable, immobile charges located structurally near the interface, caused by incomplete oxidation. Oxide Trapped Charge ( Qotcap Q sub o t end-sub

At high frequencies (typically 1 MHz), minority carriers cannot generate or recombine fast enough to keep up with the AC signal. The capacitance drops to a minimum value in inversion. The 1982 text by remains the most cited

E.H. Nicollian and J.R. Brews gave us the language to speak to the silicon. Keep their text close, master the C-V curve, and respect the "hot" carriers—because they are not going away.

For decades, the MOSFET was a purely planar device, with the gate sitting flat on top of the silicon surface. However, as gate lengths shrank below 20nm, the ability of the gate to control the "off" state of the transistor deteriorated due to "short-channel effects."

The single most important technological reason for the success of silicon-based electronics is its native oxide, silicon dioxide (SiO₂). Unlike most other semiconductors, silicon can be thermally oxidized to form an exceptionally stable, high-quality, and nearly defect-free insulating layer directly on its surface. This thermal oxide is grown by exposing a silicon wafer to high-purity oxygen or water vapor at high temperatures (typically 900°C to 1200°C).

For decades, thermally grown SiO₂ was the ideal gate oxide due to:

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.

By comparing experimental high-frequency and low-frequency C-V curves against calculated ideal curves, engineers can extract the total flatband voltage, oxide thickness, substrate doping profile, and interface trap density distribution.
