Hertz Elastic Contact in Spherical Nanoindentation Considering Infinitesimal Deformation of Indenter

Kang S.-K., Kim J-Y, Kim Y.-C., Lee Y-H, Kim J-Y, Kim Y.-C., Kwon D., Seoul National University, KR

Many studies have been performed to identify and analyze unusual nano-scale phenomena. Violation of Hertz elastic contact between the spherical nanoindenter and metallic materials has been discussed in previous studies. The unexpected results obtained using [...]

Effects of Random Work Function Fluctuations in Nanoszied Metal Grains on Electrical Characteristic of 16 nm High-/Metal Gate Bulk FinFETs

Cheng H-W, Chiu Y-Y, Lee Y-H, Li Y., National Chiao Tung University, TW

High-/metal gate (HKMG) is one of key technologies for sub-45-nm generations in nano-CMOS era [1-2]. However, using HKMG may introduce random work functions (WKs) on device’s metal gate due to various metal grain orientations [3-5]. [...]

Effects of centrifugation on the carboxyl modified single-walled carbon nanotubes suspension

Lee B.C., Lee J.A., Lee S.M., Lee Y-H, Lee B.C., Lee J.A., Lee S.M., Lee Y-H, Lee B.C., Lee J.A., Lee S.M., Lee Y-H, Paek K-K, Ju B.K., Lee B.C., Lee J.A., Lee S.M., Lee Y-H, Korea Institute of Science and Technology(KIST), KR

In this paper, the properties of supernatant samples obtained go through steps of acids oxidation and centrifugation is characterized by UV-VIS-NIR spectroscopy and Raman spectroscopy. The ultraviolet-visible-near infrared absorption spectra of each sample show the [...]

Enhanced Gene Delivery Efficiency in Resonant Acoustic Fields

Lee Y-H, Peng C-A, University of Southern California, US

Enhancement of DNA delivery efficiency has been improved by several physical and chemical approaches in the past decade. However, the application of those methods is hampered by large-scaled configurations. To augment gene delivery efficiency with [...]
