Ushbu tadqiqotda Si va SiO₂ sirtlarida hosil qilingan SiMe va SiO₂SiMe tipidagi yupqa plyonkalarning strukturaviy tuzilishi, elektrofizik va optik xossalari kompleks ravishda tadqiq etildi. Yupqa plyonkalar zamonaviy depozitsiya usullari asosida sintez qilinib, ularning mikro- va nanostrukturasi, kimyoviy bog‘lanishlari hamda sirt morfologiyasi turli fizik tahlil usullari yordamida o‘rganildi. Olingan natijalar SiO₂ asosidagi plyonkalarning asosan amorf tuzilishga ega ekanligini, Si bilan modifikatsiyalangan tizimlarda esa nanokristall kremniy klasterlari hosil bo‘lishini ko‘rsatdi.Elektrofizik o‘lchovlar plyonkalarning elektr o‘tkazuvchanligi, dielektrik parametrlar va zaryad tashuvchilar transport mexanizmlarining ularning tarkibi va strukturaviy holatiga bevosita bog‘liqligini aniqladi. Xususan, Si miqdorining ortishi natijasida zaryad tashuvchilarning energiya to‘sig‘idan kvant yo‘l bilan o‘tish ehtimoli oshishi va o‘tkazuvchanlikning sezilarli darajada ortishi kuzatildi.
