description

Slāpekļa vakances centrus dimantos var izmantot, lai noteiktu materiālu iekšējo spriegumu, temperatūru un elektrisko lauku mikroskopiskos telpas apvidos, kā arī, lai novērotu zemu koncentrāciju paramagnetiskās molekulas un jonus, kuru magnētiskais lauks samazina T1 relaksācijas laiku. Slāpekļa vakances dimantos rada ar apstarošanu, parasti ar elektroniem vai citām daļiņām, kuru enerģija ir ap dažiem megaelektronvoltiem. Pētījumā tika izveidoti dimanta paraugi, izmantojot zemas enerģijas elektronus ar transmisijas elektronu mikroskopu, kas ļauj veidot punktveida struktūras dimantā. Pētījumā divos paraugos T1 laika mērījumi atšķirās. Šajā bakalaura darbā autors salīdzināja divus dažādus dimantu paraugus, un pētīja iespējamos iemeslus šīm atšķirībām.
