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 [...]

Molecular Simulation of the Nanoscale Water Confined between an Atomic Force Microscope Tip and a Surface

Choi H.J., Kim J-Y, Hong S.D., Ha M.Y., Jang J., Pusan National University, KR

Under ambient humidity, water condenses as a meniscus between an atomic force microscope (AFM) tip and a surface, giving rise to a strong capillary force on the tip. We performed a molecular dynamics simulation of [...]

Fabrication of Metal Oxide Coaxial Nanotubes using Atomic Layer Deposition

Jeong D-K, Oh T-K, Shin H-J, Jung W.-G., Lee J-G, Sung M-M, Kim J-Y, Kookmin University, KR

We fabricated of nanotubular structures of TiO2 and ZrO2 using the gas-phase fabrication method atomic layer deposition (ALD) with nanoporous structure of polycarbonate (PC) templates. Contact printed alkylsiloxane monolayers on both sides of PCs were [...]
