aine, mille eritakistus toatemperatuuril on suurem kui metallidel ja väiksem kui dielektrikutel ... Temperatuuri tõustes pooljuhi elektritakistus väheneb; see on pooljuhti metallist eristav oluline tunnus.
a material - such as silicon - whose electrical conductivity is between that of a metal and an insulator
a material whose total conductivity, due to charge carriers of both signs (i.e.electrons and holes) is normally in the range between that of metals and insulators, and in which the charge carrier density can be changed by external means
