Polycrystalline \({\hbox {La}}_{1-x}{\hbox {Sr}}_x{\hbox {ZnAsO}}\) (0.00 \(\le \) x \(\le \) 0.075 ) was synthesized by solid-state reactions followed by hot pressing. The sign of the Seebeck coefficient changed from negative to positive by Sr doping, indicating that holes were successfully doped as a result of Sr substitutions. The maximum power factor of 0.118 mW/m K\(^2\) was attained at \(T = 747\) K in \(x = 0.05\). The thermal conductivity was relatively low at \(T = 773\) K, with a value of approximately 1.9 W/m K independent of Sr doping. These results led to a dimensionless figure-of-merit ZT of 0.044 at \(T = 747\) K in \(x = 0.05\).

多晶硅\（{\ hbox {La}} _ {1-x} {\ hbox {Sr}} _ x {\ hbox {ZnAsO}} \）（0.00 \（\ le \） x \（\ le \） 0.075）通过固相反应，然后热压合成了α-烯烃。通过Sr掺杂，塞贝克系数的符号从负变为正，这表明由于Sr置换成功地掺杂了空穴。在\（x = 0.05 \）中的\（T = 747 \） K时，获得最大功率因数0.118 mW / m K \（^ 2 \）。导热系数在\（T = 773 \） K时相对较低，其值独立于Sr掺杂约为1.9 W / mK。这些结果导致在0.044时无量纲的品质因数ZT为0.044\（T = 747 \） K in \（x = 0.05 \）。
