does anyone know what this is?

[Testin da Cable]

I was reading a document and the term 'phonon scattering' (sp) came up. What is it? Googling only reveals highly technical (scary) things that I can't get my brain around this early in the morning :/

answers in plain english please

It's where you have some phonons, and you scatter them.

 

[Testin da Cable]

that's about how far I understood some uni bloke's dissertation....

I don't want to go to russia I want a really easy explaination re whatever a phonon is

 

[Clowneh!]

Rambling bullshit.

Sorry, I feel all psycho today

 

[Testin da Cable]

I had that yesterday

Technically, a phonon is a quantum particle much like a photon, except there's a "n" where the "t" should be.

Phonons where invented by Dr Worzel Gumboot in 1926, when the "n" hammer on his typewriter got stuck to the "t" one whilst composing an angry letter to Einstein saying that wave theory was preferable to particle theory because he'd just been to the seaside.

Transposition of the "n" and "t" phenomenon is explored in the science of grammatical and spelling mistakes, as pioneered by Professor Bob the Angry Flower.

Is the temp fit?

[leggy]

Haven't read the rest of the thread but phonons are basically vibrations in a crystal lattice.

What the hell are you reading stuff like that this early for?
You should be studying the cartoons, or the sports page or something, not wading through physics papers!!!!
And no I don't know what it is. Does it affect my life? No? Do i care about phonon scattering? No. Can it make me rich or EVEN sexier? No?

Mind you I'll probably get an email in my hotmail account saying something like "Phonon scattering can give you extra inches!" or "Grow bigger breasts with new Phonon Scattering!"

Well afaik a crystalline structure is a lattice (think honeycomb*) and most of the properties are linked to that fact. so bascially they're the wave-state version of a particular quantum partical.

*The closest I could think of at the moment.

yea coz that definition REALLY helped

just imagine ur talking to a two year old when ur describing things to me, thats my brain capacity.

 

[doh_boy]

erm.... that would assume that I actually knew this stuff though :s

WELL

most solid material structures (as in how the atoms are arranged) is in the familiar 'box' pattern. Rows of atoms connect like a cube (or box). With a crystal its a 'lattice' which is pretty much a honey-comb idea. (A lot of man-made structures use a lattice due to its strength)

this ok if not ask xane he'll know. He knows everything....the know-it-all-bastige

 

[Testin da Cable]

A phonon is a quantized mode of vibration occurring in a rigid crystal lattice, such as the atomic lattice of a solid. The study of phonons is an important part of solid state physics, because they contribute to many of the physical properties of materials, such as thermal and electrical conductivity. For example, the propagation of phonons is responsible for the conduction of heat in insulators, and the properties of long-wavelength phonons gives rise to sound in solids.

According to a well-known result in classical mechanics, any vibration of a lattice can be decomposed into a superposition of normal modes of vibration. When these modes are analysed using quantum mechanics, they are found to possess some particle-like properties (see wave-particle duality.) When treated as particles, phonons are bosons possessing zero spin.

I got that far before my brain's cooler went onto overdrive. I shall read the rest of the article this afternoon. Thanks for the link Will.

I must say though...Professor Xane's explaination is much more apt, leading me to believe that people who overly stuff their papers with nasty tech/phys speak are quite silly while nice men who like cats and speak of Bob the Angry Flower shall rule the world by proxy when I am king.

I swear I saw Mr Spoon scattering phonons in one episode of Button Moon. They are small glittery pieces of foil.

and then they grew into phonon trees...yes i remember that episode.
The writter was obviously way ahead of the scientific world at that time. Move over Einstein!

 

[Testin da Cable]

hmm trees of crystal. I'd not mind wandering through a crystaline forest, but I expect it could get nasty is the sun came out in force :/

 

[Jonaldo]

It's ok, the sun is just a bigger and brighter button than the moon. Not too dangerous to phonon trees, except maybe on every other Wednesday.

 

[Testin da Cable]

hmmm my caffeine levels are much lower than yesterday

Yeah don't worry, because phonons are very very tiny, so the tree's themselves only grom to a maximum height of two angstroms.

 

[Testin da Cable]

pfft silly everyone knows you can't have an angstrom-high forest!

 

[The_Sheriff]

Wellllllll it was only a piece of fiction...
Based on a little fact.... Mr Spoon actually DID get to the moon before the Americans.

 

[Tenko]

Was the article about Intel stating they will be making smaller transistors on their next gen chips (or next, next gen etc) due to the new resistor coatings they've developed?

Apparently they've sorted out the electron leakage while avoiding the phonon resonance thingy.




I could hardly believe I actually new what you were talking about even if I'm a bit vague on what a phonon is!
