On September 25, 2014 the authors of the above mentioned paper were informed on the fact that two of the four investigated samples have had actually different fabrication history and consequently different morphology than supposed during the measurements and writing the paper. These samples are Both-B (SRC and SiC layers doped with boron) and SRC-B (boron introduced within the SRC). The boron doping was correct as described in the text; however, the samples were not annealed so that the samples contain rather amorphous ...
