Basic structure of a -channel MOSFET with electrons removed from the interface due to the quantum-confinement effect.
Random motion in zero-field transforms to a streamlined one as extremely high electric fields are encountered.
The populated valley (filled) with quantum confinement in the -direction with projection on the plane with isotropic effective mass .
The ultimate saturation velocity as a function of gate voltage. Also shown are the drain velocity and the effect of the quantum emission between the quantized levels.
Electric field profile (dotted) with partial saturation and that (solid) with full saturation .
The ratio of the drain velocity as a function of drain voltage beyond the onset of saturation for (topmost curve), 0.8, 0.9, 1.0, 1.1, and 1.2 (bottom curve).
