NOVELTY - Composite comprises many one-dimensional semiconductor nanocomposites. Each of the one-dimensional semiconductor nanocomposite comprises: at least one semiconductor medium; and at least one highly conductive nanostructure. The highly conductive nanostructures are dispersed within the each of the one-dimensional semiconductor nanocomposite, and are covered substantially by and interfacially bonded to the semiconductor media, leading to improved electrical conductivity of the one-dimensional semiconductor nanocomposite. The nanocomposites are multiwall carbon nanotubes (101).    USE - The composite is useful for electric charge transport and in solar cell, photocatalyst, nano-transistor, chemical sensor, biological sensor, humidity sensor, or lithium-ion battery.    ADVANTAGE - The highly conductive composite: provides fast electric charge transport; reduces the rate of electron-hole recombination, ultimately increasing the power conversion efficiency for use in solar cell; provides fast electrons transport, storage of electrons and large surface area for adsorption and reaction sites of active molecular species taking part in photocatalytic reaction; enhances the sensitivity of a surface for biological and chemical sensing purposes for use in biological and chemical sensors; and lowers the impedance and increases the charge storage capacity of a lithium-ion battery.
