Abstract

In Bi2Te3 materials the natural nanostructure (nns) with a wavelength of 10 nm can be reproducibly switched ON and OFF by Ar+ ion irradiation at 1.5 and 1 keV. Controlled formation of the nns in Bi2Te3 materials has potential for reducing its thermal conductivity and could increase the thermoelectric figure of merit.
