Monoatomic and monocrystalline layer of large size, in diamond type carbon, and method for the manufacture of this layer. According to the invention, a monocrystalline substrate () is formed in SiC terminated by an atomic plane of carbon according to a reconstruction c(2&#xd7;2) and at least one annealing is carried out, capable of transforming this atomic plane, which is a plane of dimers C&#x2261;C (4) of sp configuration, into a plane of dimers C&#x2014;C (8) of spconfiguration. Application to microelectronics, optics, optoelectronics, micromechanics and biomaterials.

A highly oxygen-sensitive silicon layer ( ) is formed on a substrate ( ) of, for example, SiC. The layer ( ) has a 4&times;3 surface structure. The silicon layer ( ) is deposited on a surface of the substrate ( ) in a substantially uniform manner. The highly oxygen-sensitive silicon layer of the present invention may be used, for example in microelectronics.

Silicon layer highly sensitive to oxygen and method for obtaining same

Atomic wires of great length and great stability are formed on the surface of a SiC substrate as straight chains of dimers of an element chosen from amongst SiC and C. In order to produce same, layers of the element are formed on the surface and the assembly is constructed by means of annealings of the surface provided with the layers. The resulting wires have application to nanoelectronics.
