主題:Device Architectures for Single Walled CNT Sensors and NO2 Measurement Results
內容簡介:We report on the concept of applying single walled carbon nanotube field effect transistors (SWNT FETs) as functional building blocks in gas sensors. Advances in the device architecture, fabrication processes as well as better understanding of the behavior of SWNT FETs has enabled the vision of using individual-tube devices directly for NO2 gas sensors. Significant progress has been made in understanding the sources of drift and hysteresis, and techniques have been introduced to counteract. Reducing the presence of process residues and dielectrics close to the SWNT to the best possible level leads to the suppression of hysteresis and significant improvement in the noise performance as well as improvement in the cross-sensitivity to humidity. Suspended devices are also attractive for self-heated, ultra-low-power architectures.
