Скачать или смотреть Boltzmann's Tyranny and Quantum Tunneling: The End of Computing?

In this video we'll learn about how quantum mechanics and Stefan Boltzmann are conspiring to kill viral cat videos!... or something like that.

Technical Caveat #1: I'm intentionally ignoring an entire side of the story. In reality, there are also electrons in the drain, and because it is a fundamental aspect of quantum mechanics that two electrons can't share the same state, these electrons “block” electrons from crossing the channel if no voltage is applied. In general, the role of this “blocking” is very important to understand to get a complete picture of what's happening here, but I chose to ignore it to make the specific points I was trying to emphasize conceptually clearer.

Technical Caveat #2: In general, these dates are quite soft. I'm not trying to be a historian, and am being pretty generous in some rounding and such.

Technical Caveat #3: In this whole section of the video, I'm trying to emphasize the direct parallel between classical frustrated total internal reflection (and evanescent fields) and quantum tunneling. However, there are things – like polarization, most notably – that are different between these two, and that difference is playing a role in the images I'm showing. So I'm aware that it may not be entirely fair to say the “bleeding” light shown in the photographs is tunnelled light.

Technical Caveat #4: Not all of the years I mention here were full meetings, some were just “updates”. Furthermore, I intentionally neglected to mention that there IS a new rebooted roadmap that is trying to recover from the ashes of the ITRS, so industry collaboration in this regard isn't fully 100% dead as I imply. But my point still stands.

Technical Caveat #5: People who know quite a bit about emerging solid-state technology might have heard that a 1:1 relationship between gate voltage and barrier lowering actually ISN'T the theoretical limit. There's a very good chance I might talk about so-called “negative capacitance” at some later date.

Technical Caveat #6: Throughout I only talk about the Boltzmann distribution, even though it should more accurately be the Fermi-Dirac distribution. I do this: because the two are equivalent in semiconductors in technological scenarios; because industry exclusively thinks in terms of Boltzmann; and because, well, that's where the NAME (Boltzmann's Tyranny) comes from! Also, the Density of States I draw, which I call “perfect”, that actually isn't what would be ideal for switching. But, I think it reflects the idea without dragging things down into a discussion of what would actually be an ideal switching DoS.

Technical Caveat #7: For those with a deeper knowledge of transistor physics, you might think I'm being misleading here as I'm blurring supply voltage vs. overdrive voltage, as well as supply voltage vs. gate voltage and am also avoiding a discussion of threshold voltage in general. I think the specific wording I've chosen conveys the correct ideas, without having to bog things down in delineating the specific differences and how each effect affects each differently. But others are free to disagree.
