Materials of the future-carbon atom wires whose conductivity can be changed by pulling
Time of Update: 2022-06-20
. The results show that when the carbyne is elongated, the carbon-carbon bonds tend to become unequal lengths (because the potential energy barrier between the 1:3 and 3:1 bonding structures becomes higher, making the carbon-carbon atom vibration impossible If you cross the energy barrier, you can’t step on two boats, but can only be distributed in one of them (see the above picture on the right).
