ABSTRACT
In this study, we show that systematic molecular control over a silicon-on-insulator field effect transistor (SOI-FET) device can be achieved by controlling the Si–O–Si intermolecular interactions between adjacent trichlorosilane molecules. This is attributed to the fact that Si–O–Si intermolecular bonds between the parallel molecular dipoles change the overall charge distribution within the organic layer, and, consequently, alter the channel surface potential. Changes in the potential within the formed monolayer close to the channel alter the source-drain current and, consequently, the transistor threshold (turn on) voltage.

    We report a strong Stark effect in electroluminescence (EL) from thin silicon-on-insulator metal-oxide-semiconductor field-effect transistors. The EL peak shows a large Stark shift of up to 50 meV when a gate-induced electric field is applied. Such a large shift is observed because of the strong...
