More on Spintronics
segment writes "'We have discovered the equivalent of a new 'Ohm's Law' for spintronics - the emerging science of manipulating the spin of electrons for useful purposes,' says Shoucheng Zhang, a physics professor at Stanford. 'Unlike the Ohm's Law for electronics, the new 'Ohm's Law' that we've discovered says that the spin of the electron can be transported without any loss of energy, or dissipation. Furthermore, this effect occurs at room temperature in materials already widely used in the semiconductor industry, such as gallium arsenide.'"
In Soviet Russia, the electron spins you
[Fuck Beta]
o0t!
Man it seems like that stuff NEVER goes away. Haven't we invented 10 technologies to get rid of that stuff already?
The applied electric force, the spins and the spin current align in three different directions that are all perpendicular to each other ''This is a remarkable thing,'' explains Zhang. ''I push you forward and you move sideways - not in the direction that I'm pushing you.''
Same thing happens with me after about a six pack.
In maybe a 10-year timeframe, spintronics will be on par with electronics
If the actually manage to go from idea to commerically competitive "spintronic" circuitry in only a decace, I'll consider that proof of some sort of space-alien technology transfer deal going on.
Gentlemen! You can't fight in here, this is the War Room!
I had a prof in college who loved to tell the tale of finishing his bsee at mit, and didn't know what to do next. Being young and stupid (his words) he went down to the army recruiting office and inquired about electronics. The guy behind the desk says he has to come back the next week to take a test.
So, he shows up with a bunch of other hopefuls (again, his words), and takes the test. One of the questions is 'state the 3 forms of Ohm's law." As a good ee, he immediately writes down 'V = IR', no problem. Thinking (!!), he remembers there is a form involving current density, and sets about to derive it (in class this included the steps he took). Now, a third form. He drew a blank, so went and finished other parts of the test.
Coming back to this question, he's suddenly inspired by remembering something based on magnetic density in a coil or transformer. Again, he sets out to derive the equation, but the guy giving the test says 'times up' before he can finish.
The next day, he heads back to the recruiting office, and asks how he did. "Great," says the sargeant, "but, what was up with the Ohm's law question?"
"Oh, the standard form, and then experessed in current density, and...."
"Nah, all we wanted was V = IR, I = V/R, and R = V/I."
Proof of, once again, that engineers, like musicians should not try to be funny.
Maybe now O'Reilly can finally deliver on his 'no spin zone' promise.
Of course, if all his electrons stopped spinning it would probably be the most interesting televised farewell I've ever seen.
If you're messing with electron spins, forget superconductivity and that stuff.
I want a Spindizzy.
(ref: James Blish, "Cities in Flight")
The living have better things to do than to continue hating the dead.
I've re-read Cities in Flight at least three or four times and see this spintronics stuff would make the spindizzy engine work. All we need now is a way to break New York City free from it's base of bed rock, and send it on it's way. Then Washington, D.C. whilst Congress is in session, and I see a Win-Win situation here. Hell, let's just spin off the whole Northeast corridor from The Beltway to Boston and be done with it.
Too lazy to create a sig...
> The discussion on spin is wrong.
So then what you're saying is, the article is all spin?
No, no, he's right, that's why you always put the wings on upside-down.
