  metallic transition
This photo induced metallic transition from a semiconducting state leads to a non persistent colossal photoconductivity (several orders of magnitude of decrease of the resistivity).
      
A semi-conducting/semi-metallic transition was observed for θp≈1400 °C related to the decomposition of the amorphous Si-C-N-O material and formation of free carbon.
      
The semiconductor to metallic transition is induced by chemical alloying of SmSe with SmAs similar to that observed under pressure.

Pyridine was selected as a model substrate in order to evaluate the HDN catalytic activity of nitrides synthesized above. It was found that CoMoN Ⅰ possesses conspicuously high pyridine HDN activity as compared to that of CoMoN Ⅱ, CoMoN Ⅲ and MoN Ⅳ.
