Chemical stability enhancement of lithium conducting solid electrolyte plates using sputtered LiPON thin film

Sputter deposition of LiPON films directly onto high Li+ conductivity solid electrolyte plates has been investigated as a means to minimize the reactivity of the plates to metallic Li. The LiPON films were shown to effectively passivate the plates in contact with metallic Li, in contrast to unpassivated plates that reacted immediately in contact with Li metal.

Investigation of the properties of electrochemically depositied semiconductor materials for thermoelectric applications

At JPL, it is our desire to fabricate thermoelectric micro-devices for power generation and cooling applications using an electrochemical deposition (ECD) technique. We believe that the performance of our current micro-device developed is limited by the properties of the ECD materials.

Temperature effects on polymer-carbon composite sensors

At JPL we have investigated the effects of temperature on polymer-carbon black composite sensors. While the electrical properties of polymer composites have been studied, with mechanisms of conductivity described by connectivity and tunneling, it is not fully understood how these properties affect sensor characteristics and responses.

Temperature effects on polymer-carbon composite sensors: evaluating the role of polymer molecular weight and carbon loading

We report the effect of environmental condtions coupled with varying polymer properties and carbon loadings on the performance of polymer-carbon black composite film, used as sensing medium in the JPL Electronic Nose.
