Shanghai Municipality: Program for High-Level Overseas Talents Introduction 
Dr. Jicheng Feng obtained his PhD with Prof. A. Schmidt-Ott from Delft University of Technology in 2016 on “Scalable spark ablation synthesis of nanoparticles: fundamental considerations and applications”. He then worked as a postdoctoral researcher in the group of Prof. M. Koper at Leiden University for about 2 years. In 2018, he joined the group of Prof. M. Choi at Seoul National University, where he was employed as research assistant professor. Since September 2020, he has worked as a tenure-track Assistant Professor (PI) at ShanghaiTech University, where he leads the Aerosol Intelligence Laboratory (AIL).

The semiconductor industry is facing a new era in which device downscaling and cost reduction are becoming technologically impossible tasks. Nanotechnology scientists and semiconductor companies are now looking for solutions to bridge the related gaps and improve cost performance. Our group focuses on the development of a new aerosol-based 3D nano-printing technique that enables the controlling of the geometries of electric field lines at nano-scale, and the resulting nano-path guides the charged nanoparticles to a precise location in each dimension. Our main aim is to realize its automation and then to make a smart integration into nanomanufacturing lines, which will benefit to the fields of photonics and microelectronics.

Metamaterials
Our main focus lies on the metamaterials. Micro/nano optics pushes the development of nanostructured materials that respond to light of short wavelengths. Such development has reached the limit with respect to the material types and their manufacturing. To overcome these problems, our group relies a new nanomanufacturing technology, which can be adapted to show the ability of materialization and structuring. With that, we are busy to understand the light-matter response, exploring the resulting new phenomena. This study can lead to an opportunity of breaking through the diffraction limit. 
描述
Our research mainly focuses on the creation and understanding of the behaviors of atomic clusters, also named as superatoms. For nanoparticles below a critical size (∼100 nm), their properties are not sensitive to the addition or removal of a single atom. As for atomic clusters, their properties change abruptly and nonpredictively, a stage in which even the addition of a single atom or electron may cause a drastic change. In this regime, the electron wavelength becomes comparable to the cluster size. The fact that properties of matter at this length scale are fundamentally different from their bulk behavior can be effectively used to produce materials with tailored properties. Such cluster-assembled materials, with their unique properties, can expand the scope of materials science.

We mainly focus on the printing of memory alloy nanostructures, thus adding a new dimension to our 3D printing technique. The appearance of memory alloys represents a paradigm shift in materials science. In distinct from the conventional ways, my project will implement aerosol systems to dig out new physics underlying such new possibilities. Despite the challenging tasks, the interdisciplinary research marks a frontier direction in 4D nanoprinting.

We focus on the design and creating of nanoelectronics that were incapable by other techniques. Again, we stress the strong ability of Faraday 3D printing in miniaturization and materialization. Such important features open new pathways for printing the new generation of nanoelectronics. Doing so is expected to develop a wholly new field.

We are working on developing the new generation of nanoelectronics. Such an interdisciplinary research relies on our Faraday 3D printing technique, particularly its strong abilit in printing 3D metal nanostructures with a feature size of sub-100-nm and in unlimited choice for materials.  We expect that our research will open uncharted area in printed nanoelectronics.

Sparking mashup breaks the miscibility limit in materials, and realizes vapor–crystal transformation to form "impossible" alloys of any compostion. The resulting nanoparticles flying in gases can be thought as the  "gas-ink" for 3D printing, avoding the use of any liquid. This emerging technology enables the 3D-printing of desired nanostructures with the sizes having the wavelength of visible light or even shorter ones.  Therefore, we will investigate anomalous behaviors of their interactions with light of different wavelengths.

The Faraday 3D printing technique realizes the arrangement of charged aerosol nanoparticles at each dimension. We mainly work on the printing of nanoparticles with electric fields. In this way, we succeed in fabricating of 3D-nanostructures in an array form (eg., approximately 10 000 nanostructures in one pass). Besides, we can also print complex structures via changing the shape of electric field lines. This 3D printing technique has the unique characteristics of high precision, multi-materials and fast printing speed. Therefore, this 3D printing technique will open new horizons in  nanoelectronics and nanophotonics.

Faraday 3D printing and its automation
We explore how to harness the electric field lines to print nanostructures. Combining the aerosol nanotechnology, we devised a fundamentally new printing system that allows the fabrication of arrays of nanostructures. We are committed to this interdisciplinary research to develop a new generation of nanoelectronics and nanophotonics. Not only that, such a transformative technology also provides numerous possibilities in semiconductor industries, such as making chips, creating superlens with the help of NIM et c.
