Abstract

Admittance Spectroscopic analysis was applied to study the effect of LiF buffer layer and to model the equivalent circuit for $ITO/Alq_3/LiF/Al$ device structure. The admittance spectroscopic analysis of the devices with LiF layer shows reduction in contact resistance $(R_C)$, parallel resistance $(R_P)$ and increment in parallel capacitance $(C_P)$.
