Evolution of dispersion of carbon nanotubes in Polyamide 11 matrix composites as determined by DC conductivity [PDF]

, 2012
Double-walled Carbon NanoTubes (DWCNTs) have been dispersed in a Polyamide 11 (PA11) matrix by two routes: in the solvent way, Polyamide 11 was first dissolved in its solvent to ensure a liquid state dispersion of carbon nanotubes by ultrasonic way; in ...

Electrical Noise in a TES as a Resistively Shunted Conducting Junction

Journal of Low Temperature Physics, 2012
We present results of the analysis of electrical noise in a transition edge sensor (TES) as a resistively shunted conducting junction (the RSJ model). We derive an expression for the spectral density of voltage fluctuations taking into account weak superconductivity of a TES.
