1.3 A silicon carbide single crystal exhibiting the claimed parameter values was initially presented as the invention (see original claim 1 and paragraph [0039] of the appliion). There is no evidence of common general knowledge on how to routinely control the synthesis of silicon carbide single crystals in order to obtain the coination of properties defined in the claim.
Nanosecond pulsed Nd:yttrium–aluminum–garnet laser treatment is applied to alter the electric properties of free standing polycrystalline diamond substrates, diamond-like carbon (DLC), and 4H–SiC single crystal wafers. In the case of DLC samples, the laser irradiation, nitrogen doping, as well as the incorporation of cobalt into the DLC layer reduces its electric resistance. Laser
