文燎勇，于2016年在德国伊尔梅瑙工业大学获得应用物理学博士学位。从2017至今在美国康涅狄格大学从事博士后研究工作。近年来，本人主要致力于多尺度/维度复杂纳米结构加工、器件成型及其功能化应用的研究工作。专注于利用掩模板技术来实现大面积有序纳米阵列、异质结和多元纳米超结构的精确构建，将其应用于光电转换以及表面等离子体等相关领域。
到目前为止，本人在包括Nature Nanotechnology, Nano Letters, Nature Communications, Advanced Energy Materials, ACS Nano, Energy & Environmental Science, Nano Energy, Small 等重要国际学术期刊上发表研究论文33篇。到目前为止，谷歌学术论文总引用 1300 余次，H-index 为 22。
Abstract：
Heteronanostructures (HNs) that integrate two or more nanocomponents represent an important family of advanced nanomaterials due to the synergistic effects induced by direct electronic and magnetic communications between the constituent nanocomponents, which have been applied to different areas including optoelectronics, catalysis, solar energy conversion, sensing, environmental remediation, and biomedicine.
To fully exploit the synergistic coupling effects of the HNs, the development of a general methodology that enables precisely control over each nanocomponent and their interfaces is still imperative. Herein, an innovative concept was proposed to achieve large-scale arrays of HNs with high degrees of controllability for each of the sub-components, including material, dimension, morphology, and their interfaces.
This HNs concept originates with a distinctive binary-pore AAO template that includes two dissimilar sets of pores in one matrix, where the openings of the two sets of pores are towards opposite sides of the template. Using the same growth mechanism, the binary-pore AAO template can be extended to multipore AAO templates with more geometrical options.
Finally, we use these HNs in proof-of-principle photoelectrodes, transistors and plasmonic devices. The enabled HNs demonstrated here could allow us to study the structure-property relationship from the fundamentally microscopic muticomponets to assembled macroscopic array of multicomponent on a large scale.
