研究室紹介

Professor Jae-il Jang's research lab specializes in the mechanical characterization of nanomaterials, with a focus on understanding the size-dependent mechanical behavior of semiconducting nanowires and group IV semiconductors like silicon and germanium. The lab employs advanced nanoindentation and atomic force microscopy techniques to investigate nanomechanical properties, phase transformations, and deformation mechanisms at the nanoscale. A key research direction involves correlating mechanical responses with underlying crystal structures and intermolecular interactions, particularly in single crystals and nanostructured materials. The lab also emphasizes the development and standardization of experimental protocols for reliable nanomechanical testing.

Nanoindentation is a technique which can be used to measure the mechanical properties of materials with high precision, even when they are only available in small quantities. As a result of this, nanoindentation has gained the attention of the crystal engineering community, who are not only interested in measuring the properties of single crystals of organic, inorganic and hybrid structures, but also wish to correlate the measured responses with the underlying structural features and intermolecu
