摘要

在这项研究中，烧结了本征氧化锌粉末并在其中夹杂了颗粒。研究发现，由于受控掺杂，商用 p 型氧化锌的热导率低于本征氧化锌。值得注意的是，我们的研究表明，在 AlZn2O4 和 ZnP2 沉淀存在的情况下，热导率可降低 5-10 倍。这种方法为未来设计基于氧化锌的热电材料，特别是热清除应用，提供了一种可行的方法。

Thermal conductivity suppression in ZnO with AlZn₂O₄and ZnP₂for thermoelectric applications.

In this study, intrinsic ZnO powder was sintered and intercalated with particles. The resulting powder, along with a commercial p-type product, was consolidated into bulk materials, and their thermal conductivity was measured across a temperature range of 350 K-700 K. The thermal conductivity of the commercial p-type ZnO was found to be lower than that of intrinsic ZnO, attributed to controlled doping. Notably, our demonstration illustrated that the thermal conductivity can be reduced by a factor of 5-10 in the presence of AlZn₂O₄and ZnP₂precipitates. This methodology presents a feasible approach for the future design of ZnO-based thermoelectric materials, particularly for thermal heat scavenging applications.

期刊介绍： The journal aims to publish papers at the forefront of nanoscale science and technology and especially those of an interdisciplinary nature. Here, nanotechnology is taken to include the ability to individually address, control, and modify structures, materials and devices with nanometre precision, and the synthesis of such structures into systems of micro- and macroscopic dimensions such as MEMS based devices. It encompasses the understanding of the fundamental physics, chemistry, biology and technology of nanometre-scale objects and how such objects can be used in the areas of computation, sensors, nanostructured materials and nano-biotechnology.
