The mechanism of domain-wall structure formation in Ar-Kr submonolayer films on graphite
Using Monte Carlo simulation method in the canonical ensemble, we have studied the commensurate-incommensurate transition in two-dimensional finite mixed clusters of Ar and Kr adsorbed on graphite basal plane at low temperatures. It has been demonstrated that the transition occurs when the argon con...

Використовуючи метод моделювання Монте-Карло в канонiчному ансамблi, ми дослiдили перехiд вiд спiввимiрної до неспiввимiрної фази у двовимiрних скiнчених змiшаних кластерах Ar i Kr, адсорбованих на графiтнiй базиснiй площинi при низьких температурах. Показано, що перехiд вiдбувається, коли концентрацiя аргону перевищує значення, необхiднi для покриття периферiй кластера. Неспiввимiрна фаза демонструє подiбну структуру доменної стiнки до тої, яка була спостережена у плiвках чистого криптону при густинах, що перевищують iдеальну ( p 3 × p 3)R30◦ спiввимiрну фазу, але розмiр спiввимiрних доменiв значно не змiнюється зi змiною розмiру кластера. Коли концентрацiя аргону зростає, склад доменних стiнок змiнюється, в той час як спiввимiрнi домени складаються з чистого криптону. Ми побудували просту одновимiрну модель Френкеля-Конторової, яка приводить до результатiв, що добре якiсно узгоджуються з результатами Монте-Карло, отриманими для двовимiрних систем. 2014 Article The mechanism of domain-wall structure formation in Ar-Kr submonolayer films on graphite / A.
