NOVELTY - A thermoelectric element, comprises: a nanocomposite formed from a core-shell nanoparticle. The shell has been densified around the core. The core-shell nanoparticle further comprises: a doped core, where the core is a first chalcogenide and is doped with a metal or second chalcogenide dopant. The shell is a metal or semiconducting compound comprises at least one element selected from Groups IV-VI. Grains of the densified metal or semiconducting compound possess an orientational direction. The dopant is integrated into the core such that energy barriers form affecting carrier mobility.    USE - As thermoelectric element comprising heat sensors, heat pumps, and thermoelectric generators for automobile (claimed).    ADVANTAGE - The method for generating the thermoelectric element enhances thermoelectric properties of devices; and uses nano-scale fabrication on thermoelectric materials to improve the efficiency of thermoelectric devices.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for generating a thermoelectric element involving: forming a nanocomposite from the core-shell nanoparticle further containing: the doped core; and densifying the shell of the core-shell nanoparticles to form a nanocomposite, VI disposed around the nanocrystal core. The doped core is formed from the steps: forming nanocrystal cores, and further: providing first chalcogenide material and at least one semiconductor selected from Groups IV-VI, where the first chalcogenide material and at least one semiconductor selected from Groups IV-VI are precursor solutions of the first chalcogenide core material; providing a dopant precursor, where the dopant is a metal or second chalcogenide dopant; mixing the dopant precursor with the precursor first chalcogenide material, at least one semiconductor selected from Groups IV-VI, and dopant precursor; and forming the nanocrystal cores. The nanocrystal cores are formed from the steps further involves: mixing telluride potassium hydroxide with lead acetate at standard atmosphere. The dopant precursor is dissolved in the lead acetate.
