Hahn Y.B., Kim J.H., Kim S-H, Park Y.K., Umar A., Chonbuk National University, KR

Well-crystallized zinc oxide nanonails have been synthesized in a large quantity via a thermal evaporation method using the metallic zinc powder without the use of any metal catalyst or additives. The detailed structural and optical [...]

Microfabricated Heteroepitaxial Oxide Structures on Silicon for Bolometric Arrays

Grishin A.M., Kim J.H., KTH Royal Institue of Technology, SE

To realize high sensitive bolometer, new material with higher TCR value is needed including the low thermal mass : small pixel size and very thin thermally isolated membrane. Mixed-valent manganese, perovskite La0.67(Sr, Ca)0.33MnO3 (LSCMO) films [...]

Nano-bending Method to Identify the Residual Stresses of MEMS Films

Hahn J.H., Kim J.G., Kim J.H., Kim Y.H., Lee H.Y., Seoul National University, KR

Surface micro-machined MEMS frequently suffer from the residual stress which might significantly decrease the performance and reliability of micro devices. It is important to accurately measure the residual stresses at manufacturing step. The Stoney’s equation [...]

Hydrodynamic Force on a Plate Near the Plane Wall

Kim J.H., Kim K.W., Kim M.U., Kwak B.M., KAIST, KR

Hydrodynamic force on a plate moving in a viscous fluid near the plane wall as a model of a microelectromechanical system(MEMS) is considered. The flow field is described by the linearized Navier-Stokes equation. The method [...]
