Preparation of the crack-free single phase (Zn1–Cd )13Sb10 by a gradient freeze method and their structural and thermoelectric properties

Thermal stability and electrical transport properties of Ge/Sn-codoped single crystalline β -Zn 4 Sb 3 prepared by the Sn-flux method

“…[11,12] In the past years, elements in the vicinity of Zn and Sb such as In, Pb, Sn, Cd, Bi, Mg, etc. were generally selected to dope the β -Zn 4 Sb 3 , [13][14][15][16][17][18][19][20] but Ge-substitution in β -Zn 4 Sb 3 has been rarely reported so far. Wang et al recently demonstrated the realization of a high thermoelectric figure of merit in Ge-substituted β -Zn 4 Sb 3 , the experimental results and theoretical calculations revealed that Ge substitution had a marked improvement on the Seebeck coefficient and the power factor.…”

Structural and Thermoelectric Properties of (Zn1-xMx)13Sb10 (M = Cu, Ag, Au and Ga)

“…The β-Zn 4 Sb 3 compound, which has recently refined to be Zn 13 Sb 10 , has attracted much attention since the discovery of the high ZT value of 1.3 at 670 K [1]. Many research works have been devoted to optimize the thermoelectric performance by substitution of the constituent elements [2][3][4][5][6][7][8][9][10][11][12][13][14]. Among the many substitution studies, the effect of Cd substitution has been investigated most intensively because the Cd substitution is the most effective to optimize the thermoelectric property.…”

“…Kuznetsov and Rowe have reported that details of the structural property of the hot-pressed (Zn 1-x Cd x ) 4 Sb 3 samples [7]. Nakamoto et al have reported the thermoelectric and structural properties of the Cd-substitution system prepared by rapid quenching and gradient freeze methods [8,13].…”
