courses.cit.cornell.eduConductivity and Resistivity The quantity is the conductivityof the semiconductor: q n n p p Conductivitydescribes how much current flows when an electric field is applied. Another related quantity is the resistivity which is the inverse of the conductivity, Units of conductivity are: Ohm-1-cm-1 or -1-cm-1or S-cm-1
