Adding fluorine atoms (yellow) to a single layer of tin atoms (grey) should allow a predicted new material, stanene, to conduct electricity perfectly along its edges (blue and red arrows) at temperatures up to 100 degrees Celsius (212 Fahrenheit).[/QUOTE]
[B]A single layer of tin atoms could be the world's first material to conduct electricity with 100 percent efficiency at the temperatures that computer chips operate, according to a team of theoretical physicists led by researchers from the U.S. Department of Energy's (DOE) SLAC National Accelerator Laboratory and Stanford University.[/B]
[B]The Path to Stanene[/B]
For the past decade, Zhang and colleagues have been calculating and predicting the electronic properties of a special class of materials known as topological insulators, which conduct electricity only on their outside edges or surfaces and not through their interiors. When topological insulators are just one atom thick, their edges conduct electricity with 100 percent efficiency. These unusual properties result from complex interactions between the electrons and nuclei of heavy atoms in the materials.
"The magic of topological insulators is that by their very nature, they force electrons to move in defined lanes without any speed limit, like the German autobahn," Zhang said. "As long as they're on the freeway -- the edges or surfaces -- the electrons will travel without resistance."
In 2006 and 2009, Zhang's group predicted that mercury telluride and several combinations of bismuth, antimony, selenium and tellurium should be topological insulators, and they were soon proven right in experiments performed by others. But none of those materials is a perfect conductor of electricity at room temperature, limiting their potential for commercial applications.
Earlier this year, visiting scientist Yong Xu, who is now at Tsinghua University in Beijing, collaborated with Zhang's group to consider the properties of a single layer of pure tin.
"We knew we should be looking at elements in the lower-right portion of the periodic table," Xu said. "All previous topological insulators have involved the heavy and electron-rich elements located there."
Their calculations indicated that a single layer of tin would be a topological insulator at and above room temperature, and that adding fluorine atoms to the tin would extend its operating range to at least 100 degrees Celsius (212 degrees Fahrenheit).
[B]Ultimately a Substitute for Silicon?[/B]
Zhang said the first application for this stanene-fluorine combination could be in wiring that connects the many sections of a microprocessor, allowing electrons to flow as freely as cars on a highway. Traffic congestion would still occur at on- and off-ramps made of conventional conductors, he said. But stanene wiring should significantly reduce the power consumption and heat production of microprocessors.
Manufacturing challenges include ensuring that only a single layer of tin is deposited and keeping that single layer intact during high-temperature chip-making processes.
"Eventually, we can imagine stanene being used for many more circuit structures, including replacing silicon in the hearts of transistors," Zhang said. "Someday we might even call this area Tin Valley rather than Silicon Valley."[/QUOTE]

The "Tin Age" doesn't have the same ring to it as the "Diamond Age" or the "Carbon Age" but if it yields these properties I welcome our tin overlords.
There's an island next to France called Jersey?!

Oh this 2d-tin thing is p.rad too I suppose.
Oh but it's still just a theory? I so hope this shit works out.

Seriously though I live so nearby how did I never hear about Jersey.
I wish I could afford to go to college so I could understand this stuff

Not many people know about us, but funny thing is we are one of the main finance centres of the world, terrorists and horribly large corporations harbour money here, and we only accept the top earning banks. Funny little place.

You don't really need to, it would be nice but it is not necessary. Getting the basics down is easy enough on your own and a lot more dedication will bring you further, but potential can sometimes lead to grants for further education.

You're on the internet, if you want to understand something simply educate yourself. There's thousands of possible ways to acquire knowledge here. Take for example Kahn Academy, or the huge knowledgebase that is Wikipedia.

Yeh that is obvious, you don't need to be eye-to-eye for that to seep through. Honestly find a book that the author doesn't treat it as an traditional text book, but more as an introduction. For example I have always wanted to understand at least the basic mathematics behind Quantum Theory, so I bought:

And now I can use simple math to measure a wavelength, and trust me, I got a G (almost a fail in UK terms) in maths

So many potentially useful applications, yet the only thing I could come up with for this is creating an alarm that tells you when your water is close to boiling.

The Tin Age does sound kind of like an intermediary between the Bronze Age and Iron Age, or alternatively a post-apocalyptic era of scavenger societies making use of the trash of the prior ages.

A perfect application for Britain, although we used to have a similar thing with kettles designed to whistle when it was boiling.

Maybe we need to revisit all our underrated metals/materials. Maybe stones will yield amazing results when combined wit hsomething else and we get to have another stone age! I know, I know I'm a genius. :eng101:

Real men can work out the speed of light from a microwave oven and some cheese on toast.
Isn't tin rare?
I didn't know metals made covalent bonds. Could anyone enlighten me?
Waaaiit... Are they 100% sure about that 100% efficiency thing? I mean, If it's true then I could theoretically create an infinite loop that carries a charge forever.
Fuck logic.
Fluorine is the best element.

Welcome to super conductance.
[QUOTE=Cakebatyr;43082168]Fluorine is the best element.[/QUOTE]
Yeah keep saying that until you have to handle it. Fluorine hates everyone, and only likes to work with people that it can make its bitch.
So are we talking about a room or even water boiling point superconductor?

Man, don't be a bitch.
Use marshmallows instead. Much more fun, and much more tasty.
Who the fuck makes a cheese toasty either not in a sandwich press or using the grill anyway?
[QUOTE=James xX;43080417]I didn't know metals made covalent bonds. Could anyone enlighten me?[/QUOTE]
you do realize that metals make up most of the periodic table right?

at least the application wasn't a weapon. a step up for technology threads in SH.
[QUOTE=wraithcat;43084497]So are we talking about a room or even water boiling point superconductor?[/QUOTE]
Yeah, if they can make this then we've got ourselves a room temperature superconductor.
[QUOTE=James xX;43080417]I didn't know metals made covalent bonds. Could anyone enlighten me?[/QUOTE]
Covalent bonds are when the atoms share a pair of electrons with each other. For many molecules this tricks them into thinking they have a full shell, so they become happy. (Atoms are happiest when they have a full shell, stability and stuff.) Covalent bonds are generally between two of the same elements or ones close to each other, and are generally between nonmetals, but metals can do it.
Ionic bonds are when one atom steals an electron from another, making itself negatively charged and the other positively charged, then it attracts together because of electrostatic attraction. This is commonly between a nonmetal and a metal.
(Been a bit since chemistry, if someone knows more feel free to correct me or add more info)
Mercury (I) Chloride used to be written as HgCl but it turns out it is actually Hg2Cl2 and the two Hg atoms are covalently bonded.
[QUOTE=Hamaflavian;43085673]at least the application wasn't a weapon. a step up for technology threads in SH.[/QUOTE]
I'm pretty sure you could use the heat property of it as a good failsafe detector in munitions/chemicals sensitive to heat.
[QUOTE=Kyle902;43085631]you do realize that metals make up most of the periodic table right?[/QUOTE]
Of course I do, it just seems like metallic bonding or ionic bonding even is what would fit here.
Isn't this a step forward towards rail guns? Or am I mistaken?
