description

Darbā apskatītas un pētītas dažādas augstas sakārtotības pirolītiskā grafīta (HOPG) gravēšanas metodes vēlamā virsmas raksta izveidošanai, kā arī izveidotas un attīstītas metodes grafēna lokšņu uznešanai uz dielektriskas pamatnes ar dažādiem spiedogiem. Gravēto HOPG struktūru kvalitātes raksturošanai, uz pamatnes uznesto grafēna lokšņu vizualizācijai un to biezuma noteikšanai tika izmantotas dažādas LU CFI pieejamās zinātniskās iekārtas. Darbs sastāv no literatūras pārskata daļas un no eksperimentālās daļas, kur aprakstītas izmantotās gravēšanas metodes, spiedogu izgatavošana, grafēna mehāniskās kontaktpārnešanas metodes un ietverti sasniegtie rezultāti. Pilnveidojot šādu ātru, vienkāršu un lētu metodi, un spējot kontrolēti uznest vēlamās formas grafēna loksnes nepieciešamajā pozīcijā uz pamatnes, pavērtos vairāk iespēju turpmākam zinātniskam darbam grafēna īpašību pētniecībā un uz grafēna bāzētu elektronisku ierīču prototipu izveidei laboratorijās.
