Thank you for your visit! Our lab focuses on synthesizing low-dimensional (2D) advanced nanomaterials and researching the appropriate semiconducting applications.

The Advanced Nanomaterials for Semiconductors Laboratory conducts both fundamental research on the synthesis and characterization of low-dimensional (2D) materials and applied research on their electronic, energy, and sensing device applications. The main research activities of the laboratory can be broadly categorized into two areas.

First, we focus on the synthesis, transfer, and interface engineering of various low-dimensional materials, including transition metal dichalcogenides (TMDs), MXenes, and oxide semiconductors, to achieve superior electrical and optical properties. Using chemical vapor deposition (CVD), atomic layer deposition (ALD), and solution-based processes, we fabricate large-area, high-quality thin films. Based on field-effect transistor (FET) platforms, we systematically investigate charge transport behavior and interface properties.

Second, we develop next-generation sensors, photodetectors, neuromorphic devices, and energy conversion devices by designing device architectures and physical models that incorporate the intrinsic properties and structural characteristics of low-dimensional materials. In particular, we study ion–electron interactions, interfacial charge trapping, and defect engineering to elucidate device operating mechanisms and propose strategies for performance enhancement.

To analyze electrical and optical properties, we utilize semiconductor parameter analyzers, photocurrent measurement systems, and spectroscopic characterization tools. Since material properties are strongly influenced by microstructure and crystallinity, we systematically establish structure–property relationships using scanning electron microscopy (SEM), transmission electron microscopy (TEM), atomic force microscopy (AFM), Raman spectroscopy, and X-ray diffraction (XRD).

Through this integrated approach, our laboratory bridges fundamental understanding of low-dimensional materials with practical device implementation and industrial applicability.
