We have demonstrated the room-temperature decomposition of light alkanes, highly stable molecules, using hot carriers generated by applying voltage to atomically thin tunnel junctions. Unlike thermal decomposition, which shows threshold behavior above a certain temperature, this reaction does not exhibit a simple threshold dependence on the applied voltage; instead, its activity is enhanced at specific voltages. In this presentation, we report the results of Raman spectroscopic analysis of amorphous carbon films formed as decomposition products, focusing on the correlation of their bonding structure and hydrogen content with the applied voltage that induced the reaction.
