Electron), 충돌에 의해 방출된 전자를 2차전자(Secondary Electron)라 한다. 2차 전자 방출은 1차 전자의 입사 조건에 따라 그 양과 방출되는 특징이 달라지며, 이는 TV의 촬상관이나 전자증배관에 사용된다.
■ BSE(Back Scattered Electron)란?
- BSE는 SE와 비슷하게 금속면에 전자를 충돌시켰을 때 금속 내부에 있
properties
investigating transition metal oxides
specific morphologies
nanostructured materials
→ the charge storage from faradaic processes occurring at the surface of the material
→ the pseudo-capacitive effect, becomes increasingly important
mesostructured materials
→ enhanced oxidation and reduction kinetics
→ the relatively short diffusion path length for ions and electrons

3D printing
3D printing or additive manufacturing (AM) refers to any of the various processes for printing a three-dimensional object. Primarily additive processes are used, in which successive layers of material are laid down under computer control. These objects can be of almost any shape or geometry, and are produced from a 3D model or other electronic data source.
Basic principles

③ Red, Green, and Blue LEDs for White Light Illumination
This LED application is structured by three chip(red, green, blue). Each chip emits three color. This structure has more strong light intensity than single chip WLED, but process is too complicate and not cost effective. And electron transfer is slow caused by 2-dimensional chip.
