ABSTRACT
The current–voltage characteristics, the temperature dependence of the dark conductivity, and the effect of oxygen exposure of C60 sandwich diodes are compared with Al and Al/LiF as electrodes. It appears that a thin LiF interlayer can help to preserve the space-charge limited conduction in C60 diodes under exposure to air, by considerably suppressing the oxygen diffusion into the C60 film and reaction at the Al/C60 interface.
