摘要

本文报道了基于DNA的薄膜场效应晶体管(TFFET)的初步研究结果。DNA分子是从鲑鱼的卵囊和卵囊中提取出来的,纯度为96%。DNA基薄膜的制备方法包括自旋镀膜、分子束沉积(MBD)、脉冲激光沉积(PLD)等。通过将DNA分子与导电聚合物(如PEDOT:PSS)以及导电纳米颗粒(如单壁碳纳米管)混合,整体载流子迁移率得以提高。以DNA基薄膜为半导电层的底栅、底触点结构的mosfet已被开发出来。

Deoxyribonucleic Acid (DNA) based BioTransistors
In this paper, we report the first results on DNA based thin film field effect transistors (TFFET). The DNA molecules are extracted from Salmon's milt and roe sacs and purified to 96%. DNA based thin films are obtained using different techniques including spin coating, molecular beam deposition (MBD), pulse laser deposition (PLD)...etc. An increase in the overall charge carrier mobility was achieved by blending the DNA molecules with conductive polymers such as PEDOT:PSS as well as conductive nanoparticles such as single wall carbon nanotubes. MOSFETs with bottom gate, bottom contact structures using DNA based thin films as the semi-conductive layer have been developed.
