Special Issue Information

Dear Colleagues,

Spontaneous self-assembly can serve as a tool for fabricating highly ordered, often intriguing structures, which can be applicable for potential applications, e.g., optical and electronic devices. In general, self-assembly includes numerous processes, from the non-covalent association of organic molecules, colloids, and nanoparticles in solution to the growth of semiconductor quantum dots on solid substrates, making it an essential part of micro- and nanofabrication technology. With a precise focus on spontaneous structure or pattern formation, an intensive study of distinct components and systems is possible. Accordingly, this Special Issue eagerly seeks to showcase research papers, short communications, research perspective articles, and review articles that promisingly provide technical improvements in spontaneous self-assembly of spatially ordered structures.

It is my great pleasure to cordially invite you to submit a manuscript for this Special Issue.

Dr. Myunghwan Byun
Guest Editor

Various high-performance anode and cathode materials, such as lithium carbonate, lithium titanate, cobalt oxides, silicon, graphite, germanium, and tin, have been widely investigated in an effort to enhance the energy density storage properties of lithium-ion batteries (LIBs). However, the structural manipulation of anode materials to improve the battery performance remains a challenging issue. In LIBs, optimization of the anode material is a key technology affecting not only the power density but also the lifetime of the device. Here, we introduce a novel method by which to obtain nanostructures for LIB anode application on various surfaces via nanotransfer printing (nTP) process. We used a spark plasma sintering (SPS) process to fabricate a sputter target made of Li2CO3, which is used as an anode material for LIBs. Using the nTP process, various Li2CO3 nanoscale patterns, such as line, wave, and dot patterns on a SiO2/Si substrate, were successfully obtained. Furthermore, we show highly ordered Li2CO3 nanostructures on a variety of substrates, such as Al, Al2O3, flexible PET, and 2-Hydroxylethyl Methacrylate (HEMA) contact lens substrates. It is expected that the approach demonstrated here can provide new pathway to generate many other designable structures of various LIB anode materials. Full article

In the past decade, perovskite materials have gained intensive interest due to their remarkable material properties in optoelectronics and photodetectors. This review highlights recent advances in micro-to-nanometer scale patterning of perovskite inks, placing an undue emphasis on recently developed approaches to harness spatially ordered and crystallographically oriented structures with unprecedented regularity via controlled self-assemblies, including blade coating, inkjet printing, and nanoimprinting. Patterning of the perovskite elements at the micro- or nanometer scale might be a key parameter for their integration in a real system. Nowadays, unconventional approaches based on irreversible solution evaporation hold an important position in the structuring and integration of perovskite materials. Herein, easier type patterning techniques based on evaporations of polymer solutions and the coffee ring effect are systematically reviewed. The recent progress in the potential applications of the patterned perovskite inks is also introduced. Full article
