intro
These days, it is important to study about the surface of the semiconductor and analyze its structure and composition. An EELS (electron energy loss spectroscopy) is one of the powerful tools for study the sample. One method to analyze the TEM data. It is the study of the vibrational motion of atoms and molecules on and near the surface by the analysis of the energy spectrum of low-energy
The optical microscope, often referred to as the "light microscope", is a type of microscope which uses visible light and a system of lenses to magnify images of small samples. Optical microscopes are the oldest design of microscope and were possibly invented in their present compound form in the 17th century. Basic optical microscopes can be very simple, although there are many complex designs w
Partial substitution of Ba by a smaller M2+ ion
unit cell volume decreases and the phase transition temperature decreases
An insulator at room temperature becomes semiconductive after doping
trivalent donars (e.g. La, Sb, Y) substitute for the Ba2+
pentavalent donars (e.g. Sb, Nb, Ta) substitute for Ti4+.

2.4. Bonjean Curve
많은 학생들이 Bonjean Curve 에 대해 답을 하지 못하였다고 하셨다. 우리 조원들도 이 문제에 대해 거의 답을 하지 못하였다고 했다. Bonjean Curve는 부력의 개념이다.
