Hozirgi vaqtda fizikada yarimo’tkazgichlar katta ro'l o ’ynay boshladi.
Yarimo’tkazgichlar metallardan elektr o ’tkazuvchanliklari kichik bo’lishi bilan farq
qiladi, Shu bilan birga yarimo’tkazgichlarning elektr o ’tkazuvchanligi metallar elektr
o ’tkazuvchanligidan farqli ravishda temperatura oshishi bilan oshib boradi.
