Ushbu maqolada kremniydan yasalgan yarim o‘tkazgichli diodlarda p–n o‘tishidagi lokal oblastlarda yuzaga keladigan issiqlik jarayonlari tahlil qilinadi. Tadqiqotda issiqlik o‘tkazuvchanlikni baholash uchun Furye qonuniga asoslangan issiqlik o'tkazuvchanlik tenglamasi qo‘llanildi. Model orqali dioddagi issiqlik taqsimoti va o‘zgarishi, ayniqsa lokal qizigan nuqtalarda, matematik jihatdan yechib chiqildi. Hisoblashlar, diod ish rejimlarida harorat gradientining muhim rol o‘ynashini va u elektr xususiyatlarga sezilarli ta'sir ko‘rsatishini ko‘rsatdi. Tadqiqot natijalari yarim o‘tkazgichli elementlarning ishonchliligini oshirish hamda termal boshqaruv tizimlarini loyihalashda foydali bo‘lishi mumkin.
