ABSTRACT
This paper introduces a simple portable dual analyzer which allows real-time ac-impedance measurements and noise spectroscopic analysis simultaneously employing one or two DAQ (data acquisition) systems together with a low noise current-to-voltage preamplifier. The input signal composed of numerous selected frequencies of sinusoidal voltages with a DC bias was applied to a DUT (device under test: CNT-FETs). Each frequency component, ranging from 1Hz to 46.4kHz, was successfully mapped to a Nyquist plot using the background of the electrical noise power spectrum. It is thus clearly demonstrated that this dual analyzer enables the real-time ac-impedance analysis and the frequency response of the carrier transport in the single walled carbon nanotube network field effect transistors (SWCNT-FETs) as a DUT.

2011년 1월 17일 Review of Scentific Instrument에 accepted 되었습니다.
작년 9월 교수님과 필수형과 김상태 교수님과 함께 약 6개월동안 미국 U.C Davis에서 있는동안
교수님의 아이디어로 시작된 이 논문이 드디여 1년여만에 Accepted되었습니다.
시작부터 마무리까지 스릴있는 과정이 많았는데요, 위기 순간순간을 잘 극복하도록 도와주신 교수님의 격려와 위로 속에서
잘 마무리 할 수 있었습니다. Simulation 부분에서 필수형이 도와주셨고, 소자 제작에 있어서 용하가 도와주었습니다.
선-후배님들과 협력속에서 마무리를 해서 좋은 결과를 얻었고, 연구실 여러 선-후배님들의 격려도 감사합니다.
이 논문으로 부터 Impedence 측정에 대해서 심도있게 공부 할 수 있었고, 앞으로의 실험에도 잘 이용할 수 있었으면 좋겠습니다.
DAQ를 이용하여, 간단하게 임피던스와 Noise를 실시간으로 볼 수 있는 기법을 설명한 논문이며, LabVIEW를 만드는데 좀 많은 시간이
걸렸지만 활용 분야는 많았으면 좋겠습니다.
연구실 구성원 모두들 화이팅 입니다.
