New components made of organic monomolecular layers
Description
This study is concerned with electrical properties of aluminium/monomolecular layers/aluminium structures made of n organic layers between 20 and 25 A each, according to the selected molecules. The properties of these layers are quite reproducible: in vacuo, the capacity is about 1/n μF/cm2, in series with a capacity of 1.5 μF/cm2 due to a natural oxide layer at the electrode surfaces. The loss angle tangent in the organic layers (10-3), which is mainly due to dipole movements, is low as compared with that in alumina (10-2). Breakdown voltages are given by the relation V (volts)=4,5.+ 0,75 n. Owing to polymerized monomolecular layers, it was possible to make structures that withstand high temperatures (150 deg C)

On a etudie des structures aluminium/couches monomoleculaires/aluminium formees de n couches ayant chacune une epaisseur comprise entre 20 et 25 A selon les molecules utilisees. Les caracteristiques obtenues sont tout a fait reproductibles: la capacite sous vide, est de l'ordre de (1/n) μF/cm2, en serie avec une capacite de 1,5 μF due a l'oxyde naturel present a la surface des electrodes. La tangente de l'angle de perte de la matiere organique (10-3) due essentiellement a des mouvements de dipoles, est faible devant celle de l'alumine (10-2). Les tensions de claquage obeissent a une relation de la forme V (volts)=4,5+0,75 n. La realisation de couches monomoleculaires polymerisees nous a permis d'obtenir des structures supportant des temperatures elevees (150 deg C)Files
