Hais txog qhov ntsuas kub tsis kam

Muab faib rau cov ntsuas kub tsis kam tiv thaiv cov hlau thiab cov ntsuas hluav taws xob tiv thaiv semiconductor, ob qho tib si yog raws tus yam ntxwv tias tus nqi tsis kam hloov nrog ntsuas kub. Cov pas ntsuas hlau yog feem ntau yog ua los ntawm cov xim ntshiab xws li platinum, kub, tooj, tooj npib tsib xee, thiab bismuth hlau lossis phosphor bronze alloys; Tus ntsuas ntsuas hluav taws xob feem ntau siv carbon thiab germanium. Lub ntsuas cua sov thev naus laus zis yog yooj yim siv thiab tau siv dav. Nws qhov ntsuas ntau hom yog los ntawm -260 ° C txog 600 ° C
