Energetics of charged metal clusters containing vacancies

Abstract: We study theoretically large metal clusters containing vacancies. We propose an approach, which combines the Kohn-Sham results for monovacancy in a bulk of metal and analytical expansions in small parameters cv (relative concentration of vacancies) and R −1 N,v , RN,v being cluster radius. We obtain expressions of the ionization potential and electron affinity in the form of corrections to electron work function, which require only the characteristics of 3D defect-free metal.The Kohn-Sham method is used to cal… Show more

“…In Refs. [36,37], we studied the energy characteristics of charged solid metal clusters and clusters containing a single vacancy in the stabilized jelly model detailing the LDM for N ≤ 270, using the Kohn-Sham method taking into account the quantization of the electron spectrum. Let us use these results.…”

“…Руководствуясь механизмом " выдувания" вакансий, будем считать, что число атомов в образце не зависит от наличия вакансий; концентрация атомов в межвакансионном объеме такая же, как и в отсутствии вакансий [7,8], а вакансии распределены в виде сверхрешетки.…”

“…Разработанный подход является более простым и прозрачным для анализа, чем основанный на правилах сумм и изложенный в [7,8]. Он дает возможность непосредственно работать в версии Кона−Шема, вычислять соответствующие производные в (30) и (32), не используя при этом градиентное разложение функционала и манипуляции с правилами сумм [7,8].…”
