Ushbu ishda tarkibli qo‘rg‘oshin-silikat shishasi asosidagi termoelektrik kompozit materiallarning elektrofizik
va termoelektrik xossalari tadqiq qilingan. Dastlabki bazaviy namuna 60% shisha + 40% tarkibidagi noyob va qimmatbaho
o‘tkazuvchan fazasi bosqichma-bosqich o‘zgaruvchan valentli o‘tish metallari oksidlari va bilan 30:10, 25:15 va
20:20 (massa bo‘yicha % da) nisbatlarda almashtirildi. Haroratning o‘zgarishi natijasida solishtirma elektr qarshiligi hamda
Zeebek koeffitsiyentining bog‘liqlik grafiklari tahlil qilindi. Natijalar shuni ko‘rsatdiki, va legirlovchi komponentlarining kiritilishi
energiya zonalarida lokallashgan holatlarni hosil qilib, polaronli sakrash o‘tkazuvchanlik mexanizmlarini faollashtiradi
va termoelektrik EYuKning ekstremum nuqtalariga sezilarli ta’sir ko‘rsatadi
