Black amorphous form of carbon
According to the researchers, Q-carbon exhibits a random amorphous structure that is a mix of 3-way (sp 2) and 4-way (sp 3) bonding, rather than the uniform sp 3 bonding found in diamonds. Carbon is melted using nanosecond laser pulses, then quenched rapidly to form Q-carbon, or a mixture See more Amorphous carbon is free, reactive carbon that has no crystalline structure.
