Elektroniskā versija nesatur pielikumusUrāna mononitrīds UN ir viens no materiāliem, kuru var izmantot kā perspektīvu degvielu IV paaudzes kodolu reaktoriem. Tā kā UN paraugos vienmēr atrodas ievērojams daudzums skābekļa piemaisījumu, nepieciešams izprast O adsorbcijas mehānismu, kā arī tam sekojošo UN oksidēšanos. Mēs pirmo reizi veicām UN virsmas un tās mijiedarbības ar skābekli detalizētu pētījumu, izmantojot DFT PAW metodi VASP programmas ietvaros. U un N vakances veidošanās enerģijas, kā arī saites enerģijas virs UN virsmas adsorbētajiem skābekļa atomiem un molekulām tika apskatītas kopā ar lādiņu pārdalīšanos, elektronisko stāvokļu blīvumu un O atomu migrācijas trajektorijām. Veiktie aprēķini ļauj piedāvāt enerģētiski iespējamo mehāni...
