无机纳米材料的多尺度超快激光制造技术

【Abstract】

Laser 3D nanoprinting is a maskless manufacturing technique, which can achieve high-resolution fabrication of diverse 3D nanostructures. However, traditional laser printing techniques are limited by the photopolymerization process and are only applicable to some photoresists. In this talk, I will introduce several additive manufacturing techniques such as photoexcitation-induced chemical bonding (PEB) and optofluidic crystallithography, which allows the 3D printing of inorganic materials including semiconductors, metals, insulators, as well as the laser direct writing of single-crystal halide perovskites. These laser manufacturing techniques open new ways for the fabrication of functional nanodevices and will find many applications such as integrated chips and near-eye display.

激光纳米3D打印是一种无掩模、高精度的微纳增材制造技术，可实现任意三维精细结构的加工制造。现有的激光3D纳米打印主要依赖于双光子聚合的原理，只适用于少数的聚合物材料，而在各种功能无机材料的制造上面临着技术瓶颈。该报告将介绍光激发诱导化学键合和结晶光刻等无机纳米材料激光制造新技术，基于这些技术，实现半导体、氧化物、金属等多种无机功能材料的激光三维纳米制造以及钙钛矿单晶的激光直写，开辟了功能纳米器件制备工艺的新途径，在片上光电器件集成、高性能近眼显示等领域具有广泛的应用前景。

多物理场耦合激光微纳加工及仿生光子学应用

【ABSTRACT】

Light or laser, with the diverse spatial, temporal, and spectral properties, enables precise delivery of optical energy to induce photodynamic chemical and physical effects. Such light-matter interactions form the foundation for various micro/nano-processing techniques. Our work focuses on multi-physical field coupled laser micro/nano processing towards advanced manufacturing of integrated photonics/electronics. By leveraging the diverse chemical and physical effects that are interrelated or coupled in the interactions between laser and matters, we propose and implement a series of new mechanisms and methodologies for laser micro/nano processing with multiple degrees of freedom regarding functionalities. This report will mainly introduce our latest progresses in multi-physical laser micro/nano processing and bionic optics, including thermal photonic micro/nano-surfaces and all-optical bio-inspired mechanical cilia devices.
