We present a study on the effect of ambient gases on the electrical properties of carbon nanofibers (CNFs). The resistances of a CNF placed horizontally on a substrate in air and in vacuum are compared. CNFs in air show much lower current capacities compared to those in vacuum. Joule heat produced by constant current stressing results in desorption of gas molecules responsible for carrier trapping,...
We present the first, fully integrated, multi-channel implementation of a patch-clamp measurement system. The system was implemented in a 0.5 μm silicon-on-sapphire process. The system can record two simultaneous cell membrane currents up to ±20 μA with a rms noise of 8 pA in a 10 kHz bandwidth. The system can compensate for the capacitance and resistance of the pipette electrode, up to 10 pF and...
