1. Introduction
We all use math every day to predict the weather, tell the time, handle money and etc. Math is more than formulas and equations, math is related with our lifes so deeply and it is almost everywhere. So our team members are interested in the application of the math, especially ElGamal cryptosystem and the application to the splicing telephone cables.
Sometimes we use math f

고속으로 표면분석가능/표면 높낮이가 심한 시료도 가능
마찰력으로 인한 이미지 왜곡/유기물 박막 측정시 시료 손상
-10nm이하 진폭으로 캔틸레버 진동
-시료손상 없음
-시료와 탐침 사이의 간격이 멀어 선명한 이미지 어렵다
-20-100nm이하 진폭 이용
-시료손상 없음/1-5
A partially ionized gas created by application of an electric field. Positive ion/electron pairs are created by ionization reactions, maintaining overall charge neutral.
Commonly, radio-frequency (RF) at 13.56 MHz is used to create the glow discharge.
Typical pressures are between 1 mtorr and 5 torr.

What is OLED?
(SM) OLED Small Molecule Organic Light Emitting Diode.
The original technology developed to exploit the light emitting property of
some organic chemicals. Has been the basis of most commercial products to
date.
