三维（3D）的弹性混合网络建立从互连的纳米和微观结构的建筑单位，在碳化材料的形式，是先进的技术应用的潜在候选人。然而，这些3D混合网络的简单和通用的方法制造是一个具有挑战性的任务，由于复杂和多个合成过程的参与。在本文中，我们展示了使用超轻且极其多孔的碳基气石墨材料作为模板，通过一步氢化物气相外延工艺生长气石墨-GaN 3D混合网络。GaN纳米和微米结构生长在Aeroplagma管的表面上，并遵循Aeroplagma模板的网络结构而没有团聚。合成的3D网络与来自两者的属性集成，即，纳米GaN结构和柔性半导体复合材料形式的Aeroplagma，可用作电子、光子和传感器应用的下一代材料。
Three dimensional (3D) elastic hybrid networks built from interconnected nano- and microstructure building units, in the form of semiconducting-carbonaceous materials, are potential candidates for advanced technological applications. However, fabrication of these 3D hybrid networks by simple and versatile methods is a challenging task due to the involvement of complex and multiple synthesis processes. In this paper, we demonstrate the growth of Aerographite-GaN 3D hybrid networks using ultralight and extremely porous carbon based Aerographite material as templates by a single step hydride vapor phase epitaxy process. The GaN nano- and microstructures grow on the surface of Aerographite tubes and follow the network architecture of the Aerographite template without agglomeration. The synthesized 3D networks are integrated with the properties from both, i.e., nanoscale GaN structures and Aerographite in the form of flexible and semiconducting composites which could be exploited as next generation materials for electronic, photonic, and sensors applications.
