研究室紹介
Professor Jae-Min Myoung's research lab specializes in the development and application of advanced 2D and nanostructured materials for next-generation electronic and energy devices. Key research directions include the design of MXene-based sensors for chemical, biological, and physical detection, the engineering of flexible and transparent electrochromic devices using viologen-based gels, and the exploration of novel piezoelectric nanomaterials such as trigonal tellurium nanowires for high-performance nanogenerators. The lab also investigates optoelectronic properties of ZnO nanostructures and innovative fabrication techniques for monolayer particle assemblies.

15Micropatternable double-faced (DF) zinc oxide (ZnO) nanoflowers (NFs) for flexible gas sensors have been successfully fabricated on a polyimide (PI) substrate with single-walled carbon nanotubes (SWCNTs) as electrode. The fabricated sensor comprises ZnO nanoshells laid out on a PI substrate at regular intervals, on which ZnO nanorods (NRs) were grown in- and outside the shells to maximize the surface area and form a connected network. This three-dimensional network structure possesses multiple g
A facile and quick approach to prepare self-assembled monolayers of water-dispersible particles on the water surface is presented. Particle suspensions in alcohols were dropped on a water reservoir to form long-range ordered monolayers of various particles, including spherical solid particles, soft hydrogel particles, metal nanoparticles, quantum dots, nanowires, single-wall carbon nanotubes (SWCNTs), nanoplates, and nanosheets. A systematic study was conducted on the variables affecting the mon
A series of ZnO films with various thicknesses were prepared on (0001) sapphire substrate by pulsed laser deposition (PLD). Scanning electron microscopy (SEM) and x-ray diffraction (XRD) analysis were utilized to investigate the effects of thickness variation on the surface morphology and the crystallinity. The electrical and optical properties of the films were also investigated as a function of the film thickness. It was found that the crystalline quality, electrical and optical properties of

Rubbing a dry powder of particles in one direction between two rubbery substrates is found to be a quick and highly reproducible, yet inexpensive fabrication technique for assembling particle monolayers with perfect spatial registry on flat or curved surfaces. The optimum rubbing conditions - pressure and speed - for a single-crystal monolayer are shown to depend on particle size. Potential applications are in biosensors, photovoltaics, and light manipulators.
Transparency of the glass substrate plays an important role in the performance of many optical and electronic devices. Herein, the authors have demonstrated a simple method to create a high performance wide–range anti-reflection layer on a glass surface by “carving” it with a hot alkali solution (95 °C). Morphology, composition, surface and optical properties were controlled by changing both the original composition of the glass substrates and etching time. Enhanced transparency (up to 97.7%) wa
