How to Capture Device Physics
Physics: Concepts involved with a device under study
(fundamental laws, logical thinking, etc.)
Model:
A physical Image of the device projected
onto your mind.
(pictures, formulas, etc.)
Modeling:
Modeling of a device is a quantitative measure of
your understanding of the device.
(calculation, data fitting, parameter extraction, etc.)
