1) General: A measure of the ability to transmit, as electricity, thermal energy,
sound, and so on.
From → conductive + → -ity suffix forming abstract nouns expressing state or condition.
Fr.: conductivité électrique
A measure of a material's ability to conduct an electrical current. It is the reciprocal of the → resistivity. Conductivity is expressed by σ = ne2l/(2mv), where n is the number of electrons per cm3 volume of the → conductor, e is the → electron charge, l is the → mean free path, m is the → electron mass, and v is the arithmetic mean velocity of thermal motion of electrons at a given temperature.
→ electrical; → conductivity.
Fr.: photoconductivité extrinsèque
Photoconductivity due to the addition of impurities or external causes.
→ extrinsic; → photoconductivity.
Šidhâzandegi, → photoconductivity; borungin, → extrinsic.
hâzandegi-ye gune-ye n
Fr.: conductivité de type n
The conductivity in a semiconductor caused by a flow of electrons, whereas p-type conductivity is caused by a flow of holes.
n standing for → negative; → type; → conductivity.
The phenomenon in which certain materials, when cooled to a sufficiently low temperature, lose all resistance to the flow of electricity.
→ super-; → conductivity
Fr.: conductivité thermale
In → thermal conduction, the amount of heat passing across unit area per unit time and per unit → temperature gradient.
→ thermal; → conductivity.
