- •
The effect of covalently bonded organic molecules on silicon surface is studied.
- •
Organic monolayer of 1-dodecyne is formed on (100) p-type silicon surface by simple chemistry.
- •
Gold-Silicon and Aluminum-Silicon Schottky junctions are formed on both unmodified and chemically modified semiconductor.
- •
Charge transport of the above junctions is systematically studied.
- •
The molecular modification is effective in controlling the surface state and hence the junction responds to the change in work function of contacting metal.
