磁控溅射法制备Si1-xGexB多层薄膜及其热电性能研究
摘要：摘要本文通过磁控溅射法制备了一种独特的SiGe/B五层结构薄膜材料，每层结构包含60 nm的Si60Ge40层和0.55 nm的B层。实验考察了薄膜材料的热电性能，结果表明：B掺杂的溅射时间最佳为30 s；当退火温度为650℃时，薄膜的致密性最好，且在此温度下具有较高的Seebeck系数，最大值为6.75 × 10−4 V/K，电阻率最小值为1.6 × 10−5 Ω•m，其功率因子最大值为0.026 W/(m?K2)。

Abstract:：Unique structure (SiGe/B) based multilayer film prepared by magnetron sputtering was designed with purposes of improving electrical conductivity and Seebeck coefficient, and reducing thermal conductivity. The multilayer film contains 5 periods and each of them consisted of a 60-nm-thick Si60Ge40 layer and a 0.55-nm-thick B layer. Its thermoelectric performance was investigated and results showed that the best doping time of B was 30 s. When the annealing temperature was 650oC, the optimized film showed greatly enhanced Seebeck coefficient up to 6.75 × 10−4 V/K with decreased electrical resistivity of 1.6×10−5 Ω•m, and the maximum power factor was 0.026 W/m•K2.
