I deleted the following paragraph:

At any given temperature, the amount of energy needed to create a vacancy is diminished because creating a vacancy disorders the interior of the crystal. The measure of this disorder is called the entropy of the system. Adding vacancies to the material increases the entropy, which tends to reduce the total energy required to create the vacancy. This energy is called the free energy and this is the energy that is required to create an equilibrium concentration of vacancies at a given temperature.

Obviously somebody here has not really penetrated thermodynamics. The ideas of what above paragraph would want to say should go back into the article, however: that vacancies have finite entropy per energy (compared to dislocations, for example), and therefore have some equilibrium concentration by the Boltzmann distribution, and incidentally are the dominating type of thermal defect.

Last week I added a section on detecting vacancies, which was removed as 'unsourced' even though pertinent wikipedia pages were linked to. If there are any reason not to expand this article, please elucidate. Deftec (talk) 04:58, 18 June 2018 (UTC)[reply]

Please see WP:reliable sources as your addition was unsourced. A link to another WP page is not a reference. Vsmith (talk) 11:58, 11 July 2018 (UTC)[reply]
