[edit]Hi there, for people unfamiliar with terms in physics, the introduction to the article reads as one big piece of jargon. Can it be rewritten for the layfolk? Eliz81(talk)(contribs) 00:49, 29 July 2007 (UTC)
- Sure! On it as soon as my exams get over. *insert groan here*
- Midterms :( Yet thank goodness we did just this last week ^_^Neeya The Great (talk) 17:20, 30 August 2011 (UTC)
No defects at 0K? Says who?
[edit]>> and it is theorized that there will be no defects in a crystal at 0 K.
Um, what? Theorised by whom? Someone with no knowledge of lattice dynamics and quenching, I'll wager. 121.45.199.81 (talk) 12:39, 24 February 2011 (UTC)
Pick up a physics textbook. Any textbook. Even a chemistry textbook. Doesn't even need to be advanced or University level. Though its there in those too. I'm doing science in the 12th grade in India, we have it in our textbooks, I'm also studying University level textbooks - there in those too. Its a theory according to which - the thermal energy of all atoms and electrons is reduced to zero, thus they do not get excited - they do not move. And without moving - this defect does not arise.
Say scientists all over the world. Neeya The Great (talk) 17:15, 30 August 2011 (UTC)
Third law of thermodynamics is this ominous theory called. Although above IP address obviously is correct, even the theory say that you cannot reach it in practice, and with any practically doable cooling rate you will be left with a vacancy concentration of some 10^-7 by considering how long it will take for excess vacancies to reach sinks where they can anneal.

This is correct at equilibrium. At equilibrium, there are no defects, as the entropy goes to zero. However, in practice, there is always some quenched-in disorder. This quenched-in disorder is often in the form of point defects that are in excess of their equilibrium concentration. 18.189.100.227 (talk) 13:33, 22 October 2015 (UTC)
