我们制作了局部电解质门控的碳纳米管场效应晶体管（cntfet），其中电解质作为局部顶栅极。电解质溶液中的局部电解质门控cntfet在亚阈值斜率和跨电导方面具有优异的性能，这是由于碳纳米管通道中的传导调制和大栅极电容。利用局部电解质门控的cntfet，成功地实现了基于通道电导调制的实时蛋白质检测。我们的局部电解质门控cntfet是纳米级电子和分子传感器件应用的有前途的候选人。
We have fabricated local-electrolyte-gated carbon nanotube field-effect transistors (CNTFETs), in which the electrolyte functions as a local top gate. The local-electrolyte-gated CNTFETs in the electrolyte solution provided high performance in terms of subthreshold slope and transconductance, resulting from the modulation of the conduction in the carbon nanotube channel and the large gate capacitance. Using the local-electrolyte-gated CNTFETs, real-time protein detection based on the channel conductance modulation was successfully demonstrated. Our local-electrolyte-gated CNTFETs are promising candidates for the development of nanoscale electronic and molecular-sensing device applications.
