In conductors, the lowest level in the conduction band happens to be lower than the highest level of the valence band and hence the conduction band and the valence band overlap. 2011 Jun 28;5(6):4401-6. doi: 10.1021/nn103200t. Some materials are good conductor of electricity that means current can pass through them very easily; again some materials do not allow current to flow through them. Copper. Free-standing gold foils with thicknesses ranging from 280–320 A are heated by a 400 nm, 150 fs (FWHM) pump laser that is focused with f=50 optics to pro-duce a focal spot diameter of 65 m (FWHM) with a Electrical resistivity and its converse, electrical conductivity, is a fundamental property of a material that quantifies how strongly it resists or conducts the flow of electric current. Salt water is chemically aggressive and water hydrolyzes above 0.4v, so the probes for high-conductivity environments are usually made of resistant materials such as platinum, titanium, gold-plated nickel or graphite, making them somewhat expensive. Gold is also known for its high conductivity, but because of its cost, it is only used in moderation. Conductivity definition, the property or power of conducting heat, electricity, or sound. ft⋅°F).. Electrical Conductivity.
