Charge transport phenomena in thin-film cathodes

Solid State Ionics, 1992
Abstract The OCV, chemical diffusion coefficient and thermodynamic enhancement factor has been determined as a function of lithium content in MOCVD TiS 2 films. The films were deposited in a cold-wall reactor at 7.5 mbar, 207 and 250°C, and a feed gas composition of 0.25 vol% TiCl 4 and 1.4 vol% hexamethyldisilathiane.
