Experimental study of thermoelectric properties of InSb nanowires

Abstract

Experimental investigation of thermoelectric properties of nanowires with diameter of about 5 nm has been carried out. Chrysotile asbestos (the natural mineral) was used for a sample preparation. Its nano-sized channels were filled in by melted InSb. The measurements have shown that temperature dependencies of electrical resistance and thermopower of produced quantum wire structures differ considerably from corresponding dependencies of bulk InSb. It has been noted that the obtained results are better described by Luttinger liquid model than by the usual Fermi gas one.
