硅纳米粒子（SiNPs）与共轭分子功能化是一个有前途的潜在途径，用于产生一个替代类别的热电材料。虽然已经证明了基于苯乙炔封端的SiNP的材料的热电性能，但是它们的低电导率仍然是它们的一般应用的问题。最近在卢瑟福阿普尔顿实验室使用HIFI光谱仪对苯乙炔封端的SiNP进行了μ子研究，测量了作为温度函数的避免的能级交叉光谱。结果表明，在室温以上的共振的测量线宽的减少，这表明该系统的激活行为。这项研究表明，μ子研究可能是研究混合热电材料微观电导率的有力方法。
Silicon nanoparticles (SiNPs) functionalized with conjugated molecules are a promising potential pathway for generating an alternative category of thermoelectric materials. While the thermoelectric performance of materials based on phenylacetylene-capped SiNPs has been proven, their low conductivity is still a problem for their general application. A muon study of phenylacetylene-capped SiNPs was recently carried out using the HIFI spectrometer at the Rutherford Appleton Laboratory, measuring the avoided level-crossing spectra as a function of temperature. The results show a reduction in the measured line width of the resonance above room temperature, suggesting an activated behaviour for this system. This study shows that the muon study could be a powerful method for investigating microscopic conductivity of hybrid thermoelectric materials.
