In Reply to: More proof of activity on the quantum level.... posted by alan m. kafton on July 18, 2015 at 21:32:58:
"the textbook characteristics of L, C, and R"...
Are not the least in conflict with any underlying mechanisms because they simply don't address them at all. They are useful characterizations that describe the nature of the beast adequately for general understanding and the initial levels of design.
The next level down in design and usage is given to fairly gross, measurable failures of "perfection". In other words all components are RLC networks despite being touted as just one of the preceeding. Component manufacturers have, over the years, refined designs and materials to where today's parts are far "purer" than ever, but they can never reach perfection as nature won't allow it.
AND THEN assuming that the parts are quite dominated by their desired characteristic, how do the attributes of that characteristic compare to the perfection that we desire? Is that resistor's noise voltage reeealy (4KTRB)^2 or does it have "excess" noise?
My (belabored?) point is that the level of detail provided by quantum mechanics, while crucial to understanding the actual physics of the beast, has little impact on design and implementation at the component level. At the semiconductor level however...
