Something wrong with 'Dutch university professors' ?!
Mind your words mister bachelor.
Sorry, apparently the Dutch have a pecking order that we don't have here in the USA. I would presume that PhD's can do no wrong, but BA's are meaningless and can be insulted at will, even with 50 years experience behind them. The only exception that I know for sure is A J Vandenhul, who is attacked by just about everybody, especially my critics. I think A J is OK.
Gonna ask about high speed resistor to some PhD's in my university, one of the best in the country, with a lot of brilliant people, but in my humble opinion the S/N ratio here is pretty much to high, need some type of filtering lol
Yes, I mispoke, the real research was done elsewhere. Dr. Wald de Heer only participated in the 1998 paper that I like best.
You should all read 'Carbon Nanotube Quantum resistors' by Frank , Poncharal, Wang and de Heer. 'Science 12 June 1998. It is a little dated, but not for most here. Maybe, it will bring some of you into the world of today's physics. Did it for me, 10 years ago. It's lonely out here. ;-)
Sorry, John, but whether Drude or QM, a resistor impedes the mobility of electrons.
And don't give me this get up to date crap when you have yet to demonstrate that you have any grasp at all of even basic quantum mechanics. All you do is throw out buzzwords and run away, never engaging in any sort of dialogue or discussion.

After 50 years most of it becomes obsolete.
As for A.J.V. he is NOT OK. Carbon speaker cables, for example. What a scam !
Tell you what, John, why don't you demonstrate that you have even the first clue what you're talking about by giving a synopsis of this paper and telling us what it's relevance is to the context of this discussion.
Then we'll talk.

This resistor 'speed' is an interesting thing. First, what would create a SLOW resistor?
Well, length for a start. I would presume that a 2 meter long resistor would be 'slower' than a 1 cm long resistor, just travel time, all else being equal. Next, perhaps inductance included with the resistor. I would think that with 2 resistors of equal length, that the lower inductance resistor would be 'faster'.
Now, I will stop there for a moment and ask a fundamental question. What is the nature of resistance? If your first assumptions are put forth, then WHY doesn't sodium, etc NOT have the same resistivity as copper, silver, etc? Do the math an see for yourself.

A little bit thicker? They are a lot thicker, they have to be to lower the resistance. Ok, i'm not daft or rich enough to try them out myself but i get the idea of removing any metal crystal boundries. I have seen pictures of mad Japanese with troughs filled with mercury to connect their loudspeakers to amps
They probably ended up mad breathing the vapours, the same idea applies though 🙂Why can't threads stick to the original topic, even if the topic was probably nuts in the first instance 😀 I'll shut up from now on... All we appear to get from certain people are vague statements asking for people to think about certain things or look up papers. Frankly i'd rather someone explain stuff than be all coy about giving a decent reply 🙄
nuts
Apparently, you do already know the answer to this: just because this topic is 'nuts in the first instance'. 😉

That equation is for CONDUCTANCE, not resistance. Did you miss the "GO=" ahead of that equation in the article?
And what exactly does it have to do with what we're discussing here?
Again, you just throw **** up in the air hoping something sticks. That's not discussion, that's a smoke screen.
