MARGANES NANOKLASTERLI KUCHLI KOMPENSATSIYALANGAN KREMNIYDA HARORAT VA ELEKTR MAYDONGA SEZGIRLIKNING FIZIK MEXANIZMLARI
Abstract
Ushbu maqolada kuchli kompensatsiyalangan, marganes nanoklasterlari bilan modifikatsiyalangan p-tipli kremniyning harorat va elektr maydonga sezgirligi hamda bu sezgirlikni belgilovchi fizik mexanizmlar tahlil qilinadi. Magistrlik tadqiqoti natijalariga ko‘ra, material T = 77–400 K oralig‘ida ishlaydigan, termosezgirlik koeffitsienti β ≈ 9000–10000 K⁻¹ ga yetadigan yuqori sezgir termodatchik yaratish imkonini beradi; T = 240–320 K oralig‘ida esa manfiy magnit qarshilik orqali amalga oshiriladigan qo‘shimcha termik kanal (β = 7–8 %/K) mavjudligi ko‘rsatilgan. Elektr maydonga sezgirlik 2–2,5 %/(V/sm) ni tashkil etadi. Kuzatilgan yuqori sezgirlik kuchli kompensatsiyalangan materiallarga xos tashuvchilar harakatchanligining pasayishi, ularning hayot davri o‘zgarishi va mahalliy elektroneytrallikning yo‘qligi natijasida yuzaga keladigan energetik zonalar modulyatsiyasi bilan izohlanadi. Natijalar Mn nanoklasterli kremniyni ekstremal sharoitlarda ishlaydigan yuqori sezgir ko‘p funksiyali datchiklar uchun istiqbolli material sifatida qo‘llash imkoniyatini tasdiqlaydi.
