Abstract
A thermoelectric nanocomposite is provided. The thermoelectric nanocomposite includes: a matrix having n-type semiconductor characteristics and comprising Mg, Si, Al, and Bi components, and a nanoinclusion comprising Bi and Mg components.
The thermoelectric nanocomposite has significantly increased thermoelectric energy conversion efficiency by simultaneously having an increased Seebeck coefficient and a decreased thermal conductivity, such that the thermoelectric nanocomposite is usefully used to implement a thermoelectric device having high efficiency.
