WebGaAs bulk resistivity can range from 10–6 Ω-cm to about 1022 Ω-cm, with the practical range being 10–3 Ω-cm to 108 Ω-cm. This high resistivity is about six orders of magnitude greater than that of silicon and provides excellent isolation and substrate insulation. Undoped GaAs can be made semi-insulating by the addition of either oxygen The electrical resistivity of most materials changes with temperature. If the temperature T does not vary too much, a linear approximation is typically used: where is called the temperature coefficient of resistivity, is a fixed reference temperature (usually room temperature), and is the resistivity at temperature . The parameter is an empirical parameter fitted from measurement data, equal to 1/ . Because the linear approximation is only an approxi…
