Metal-Insulator-Semiconductor structures were fabricated using 40 layers thick Langmuir-Blodgett (LB) films of stearic acid (SA) on hydrophobic n-type silicon (n-Si) substrates. Samples containing cadmium sulphide (CdS) nanoparticles exhibit higher rectification than untreated ones by two orders of magnitudes. The flat band voltage Is found to be 0.5V from the capacitance measurement. The effective dielectric constant of the CdS embedded SA matrix is estimated to be 5.2.
