High-resolution transmission electron microscopy study on the growth modes of GaSb islands grown on a semi-insulating GaAs (001) substrate
- Y. Kim, J. Lee, Young-Woock Noh, M. Kim, J. Oh
- Physics
- 14 June 2007
The initial growth behaviors of GaSb on a GaAs substrate were studied using a high-resolution electron microscope (HRTEM). Four types of GaSb islands were observed by HRTEM. HRTEM micrographs showed… Expand
Improving the Performance of High Capacity Li-Ion Anode Materials by Lithium Titanate Surface Coating
Current methods for improving the electrochemical performance of lithium-ion battery electrode materials mostly depend on materials design and synthesis. We propose that the unique electrochemical… Expand
Dependence of the properties of hydrothermally grown ZnO on precursor concentration
- Xiuqin Zhao, J. Lee, +13 authors X. Sun
- Materials Science
- 1 August 2009
Abstract This study evaluated the effects of precursor concentration ranging from 0.06 to 1.5 M on the properties of hydrothermally grown ZnO on annealed ZnO buffered Si substrates. At relatively low… Expand
Effects of the annealing duration of the ZnO buffer layer on structural and optical properties of ZnO rods grown by a hydrothermal process

- Materials Science
- 30 July 2009
Abstract In this study, the effects of the annealing duration of a zinc oxide (ZnO) buffer layer on structural and optical properties of ZnO rods grown by a hydrothermal process are discussed. A ZnO… Expand
Effects of buffer layer annealing temperature on the structural and optical properties of hydrothermal grown ZnO
- X. Q. Zhao, C. R. Kim, +11 authors X. Sun
- Materials Science
- 1 February 2009
Abstract ZnO was deposited on bare Si(1 0 0), as-deposited, and annealed ZnO/Si(1 0 0) substrates by hydrothermal synthesis. The effects of a ZnO buffer layer and its thermal annealing on the… Expand
ELLIPTICAL GRAIN GROWTH IN THE SOLID-PHASE CRYSTALLIZATION OF AMORPHOUS SRBI2TA2O9 THIN FILMS
During the crystallization process of amorphous SrBi2Ta2O9 (SBT) thin films at 800 °C in a dry O2 ambient, we have found elliptical nuclei in the initial nucleation state. These elliptical grains are… Expand

- Engineering
- 1 July 1999
A new beta gauge particulate sampler with filter cassette mechanism instead of conventional filter roll has been developed for automatic measurement of mass concentration of PM{sub 10} particles in… Expand
