摘      要：The(GeTe)_(x)(AgSbTe_(2))_(100-x)alloys,also called TAGS-x in short,have long been demonstrated as a promising candidate for thermoelectric applications with successful services as the p-type leg in radioisotope thermoelectric generators for space *** largely stems from the complex band structure for a superior electronic performance and strong anharmonicity for a low lattice thermal *** of the proven strategies including carrier concentration optimization,band and defects engineering,an extraordinary thermoelectric figure of merit,zT,has been achieved in TAGS-based ***,crystal structure,band structure,microstructure,synthesis techniques and thermoelectric transport properties of TAGS-based alloys,as well as successful strategies for manipulating the thermoelectric performance,are surveyed with opportunities for further *** strategies involved are believed to be in principle applicable for advancing many other thermoelectrics.
