Method of fastening lamellae of a lamellar material on a suitable substrate

Abstract

The invention provides a method of fastening lamellae of a lamellar material that is at least partially conductive onto an insulating substrate ( 2 ) containing oxides that are suitable for dissociating into mobile ions of given charge and stationary ions of opposite charge, the method comprising the steps of: placing a sample ( 1 ) of the lamellar material against a surface of the substrate; causing the oxides of the substrate to dissociate; and subjecting the substrate and the sample to an electric field by means of an electrode in contact with the substrate and an electrode in contact with the sample.

1 . A method of fastening lamellae of a lamellar material that is at least partially conductive onto an insulating substrate ( 2 ) containing oxides that are suitable for dissociating into mobile ions of given charge and stationary ions of opposite charge, the method comprising the steps of:
 placing a sample ( 1 ) of the lamellar material against a surface of the substrate;   causing the oxides of the substrate to dissociate; and   subjecting the substrate and the sample to an electric field by means of an electrode in contact with the substrate and an electrode in contact with the sample.   
     
     
         2 . A method according to  claim 1 , wherein a substrate is connected made of borosilicate glass containing alkali oxides Na 2 O suitable for dissociating into mobile Na +  cations and stationary O 2−  anions under the effect of temperature, and wherein the substrate is heated to cause said dissociation. 
     
     
         3 . A method according to  claim 2 , wherein the substrate is heated to a temperature lying in the range [150° C., 350° C.].
