The molecules under study are deposited on the substrate (plane die) either by spin coating or by Dip-Pen-Nanolithography (DPN). The sample capacitor is completed by covering the plane die which carries the sample by the upper die which is equipped with nanostructured insulating spacers.
Evidently preparations of this kind require appropriate conditions provided by, e.g., clean rooms or clean benches. Since the surface-to-volume ratio in nanometric samples is extraordinarily high, effects due to the adsorption of, e.g., water or organic pollutants from ambient air have to considered with great care.
The Novocontrol NanoKit offers the essential parts for a straightforward start into the preparation of nanometric thin-film samples appropriate for dielectric measurements. Details of preparation are described thoroughly, rendering your sample preparations and measurements a straightforward procedure.
