: Small-signal theory, bulk traps, and electrical property measurement. Interface Trap Properties
According to , gate lengths shrunk from 10 µm (1970s) to sub-3 nm (today). Scaling brought challenges:
: Applying voltage to the gate creates an electric field that modulates the charge carrier concentration at the semiconductor interface. Operating Regimes : : Small-signal theory, bulk traps, and electrical property

Once injected, hot carriers create damage through: Operating Regimes : The Foundation of Modern Electronics:
The (developed by Nicollian & Goetzberger) remains the most sensitive technique to measure Q_it density (D_it) in units of cm⁻² eV⁻¹. State-of-the-art Si MOS has D_it < 1e10 cm⁻² eV⁻¹; early devices had >1e12.
The field of MOS physics and technology stands as one of the towering achievements of applied science. It has transformed the world, enabling the digital age from personal computers to smartphones to artificial intelligence. The iconic text by E.H. Nicollian and J.R. Brews, MOS (Metal Oxide Semiconductor) Physics and Technology , remains the definitive guide to the fundamentals of this field, a tribute to the rigorous scientific and engineering work that made the revolution possible. It has transformed the world, enabling the digital
