Hozirgi kunda texnika-texnologiyalar hayotimizda katta rol o’ynaydi. p-n oʻtishli diod va tranzistorlar texnikada keng qoʻllanilgani uchun ularning parametrlarini tashqi ta’sirlarga sezgirligini va xarakteristikalarini oʻrganish juda muhim hisoblanadi. Bu ishda p-n oʻtish volt-amper xarakteristikasiga, kuchlanishiga va potensial to’siq balandligiga magnit maydonning ta’siri koʻrib chiqilgan. Magnit maydon ortib borganda, volt-amper xarakteristikasi oʻng tomonga siljib,qarshilik ortib, kuchlanishning ham ortib borishi tajribalarda kuzatilgan va buni Xoll kuchlanishi xisobiga deb tushuntirilgan. Qarshilikni ortishi esa magnitoqarshilik effekti bilan bogʻliq. p-n oʻtish kuchlanishining magnit maydonga bogʻliq ifodasi keltirilgan va turli haroratlarda uning oʻzgarishlari ham keltirilgan. Tajribalarda harorat pasayganda magnit maydon boʻlgan va boʻlmagan hollarda kuchlanishlar farqi katta boʻlgani kuzatilgan. Harorat past boʻlganda va magnit maydoni ortib borganda kuchlanishning magnit maydonga bogʻliq ozgarishini xisobga oluvchi ifoda keltirilgan. Bu ifoda yordamida olingan grafiklar tajriba natijalari kabi harorat pasayganda kuchlanishning ortib borishini namoyon qilgan. Bu bogʻliqlikni tushuntirishda Xoll koiffitsiyentining zaryad tashuvchilar xarakatchanligi bilan bogʻliq xolda oʻzgarishidan foydalandik. Shunda Xoll kuchlanishi ham harorat kamayishi bilan ortib borishiga erishdik. Bizning olgan natijalarimiz tajriba natijalariga yaqin boʻlgan. Olingan nazariy natijalar tajriba natijalari bilan solishtirilgan va xulosalar olingan.
