We report the scaling behavior of 1/f noise in single-walled carbon nanotube devices. In this study we use two-dimensional carbon nanotube networks to explore the geometric scaling of 1/f noise and find that for devices of a given resistance the noise scales inversely with device size. We have established an empirical formula that describes this behavior over a wide range of device parameters that can be used to assess the noise characteristics of carbon nanotube-based electronic devices and sensors.

    The excess noise of single-walled carbon nanotubes is studied over the 77K to 300K temperature range. Lorentzian shaped spectra along with 1/f noise spectra are observed. From the Lorentzian noise components activation energies of 0.21 and 0.46eV for the associated fluctuation mechanisms are...

    Low-frequency noise of top-gated ambipolar carbon nanotube field effect transistors (CNT-FETs) with aligned CNT growth onto the quartz substrate is presented. The noise of top-gated CNT-FETs in air is lower than that of back-gated devices, and is comparable to that of back-gated devices in...

    The authors have developed gas sensors that operate when gas flowing through carbon nanotube (CNT) channels is adsorbed on the inner surface of the channels. CNTs fabricated on anodic alumina membranes were used. The CNTs are well ordered and connected in parallel, forming parallel channels. The...
