Abstract

Ag-doped ZnO nanorods growth on a PET-graphene substrate (Ag-ZnO/PET-GR) with different Ag-doped content were synthesized by low-temperature ion-sputtering-assisted hydrothermal synthesis method. The phase composition, morphologies of ZnO, and electrical properties were analyzed. Ag-doping affects the initially perpendicular growth of ZnO nanorods, resulting in oblique growth of ZnO nanorods becoming more obvious as the Ag-doped content increases, and the diameter of the nanorods decreasing gradually. The width of the forbidden band gap of the ZnO films decreases with increasing Ag-doped content. For the Ag-ZnO/PET-GR composite structure, the Ag-ZnO thin film with 5% Ag-doped content has the largest carrier concentration (8.1 × 10 cm), the highest mobility (67 cm · V · s), a small resistivity (0.09 Ω·cm), and impressive electrical properties.

摘要

采用低温离子溅射辅助水热合成法，在具有不同银掺杂含量的聚对苯二甲酸乙二酯-石墨烯基底（Ag-ZnO/PET-GR）上合成了银掺杂的氧化锌纳米棒。分析了氧化锌的相组成、形貌及电学性能。银掺杂影响氧化锌纳米棒最初的垂直生长，随着银掺杂含量的增加，氧化锌纳米棒的倾斜生长变得更加明显，且纳米棒的直径逐渐减小。氧化锌薄膜的禁带宽度随着银掺杂含量的增加而减小。对于Ag-ZnO/PET-GR复合结构，银掺杂含量为5%的Ag-ZnO薄膜具有最大的载流子浓度（8.1×10 cm）、最高的迁移率（67 cm·V·s）、较小的电阻率（0.09 Ω·cm）以及令人印象深刻的电学性能。
