Paper Abstract

Pentacene-based organic superlattice transistors (OSLFETs) using the monolayer (ML) thickness of organic pentacene and amorphous organic material have been studied. By changing the unit number of pentacene (2 ML) and amorphous organic layers, transistor characteristics, namely, mobility, threshold voltage and on-off ratio, were markedly changed. Under optimum stacked layer conditions, the mobility was determined to be 1.35 cm2/Vs, and the on-off ratio, 106. By changing the unit number of pentacene and amorphous organic layers, the sheet charge was determined to be 6.2×1011 cm-2. This superlattice configuration concept is expected to improve carrier transport and control the threshold voltage for an integrated circuit configuration.
