Seol, S. K., Pyun, A. R., Hwu, Y. K., Margaritondo, G., Je, J. H.
We have developed a novel strategy for localized electrochemical deposition (LECD) to improve both the lateral resolution of the process and the porosity of the fabricated high-aspect-ratio...
Imaging cells and tissues with refractive index radiology (2004)
Hwu, Y., Tsai, W. L., Chang, H. M., Yeh, H. I., Hsu, P. C., Yang, Y. C., ...
Can individual cells, including live cells, be imaged using hard x rays? Common wisdom until now required sophisticated staining techniques for this task. We show instead that individual cells and...

Localized electrochemical deposition (LECD) is an emerging technology for inexpensive and effective fabrication of high-aspect-ratio microstructure of diverse materials. Microradiology with coherent...
Synchrotron microangiography with no contrast agent (2004)
Hwu, Y., Tsai, W. L., Je, J. H., Seol, S. K., Kim, B., Groso, A., ...
Coherent x-rays from synchrotron sources are increasingly used in non-conventional radiological techniques ('phase-contrast' radiology). Our experiments demonstrate that by using white...
Metal/GaN reaction chemistry and their electrical properties (2004)
Kim, C. C., Seol, S. K., Kim, J. K., Lee, J. L., Hwu, Y., Ruterana, P., ...
We investigated the reaction chemistry of metal contacts to GaN during annealing using X-ray photoelectron spectroscopy (XPS). GaN decomposition was estimated, using XPS, to occur in N-2 annealed...
