Electrons have been caught flowing through graphene like a liquid, reaching limits physicists thought were fundamentally impossible.
This type of conductance is known as ‘superballistic’ flow, and this new experiment suggests it could revolutionise the way we conduct electricity.
If that’s not crazy enough, the super-fast flows actually occur as a result of electrons bouncing off each other, something that high school physics tells us should slow conductivity down.
So what’s going on here? For decades, scientists had speculated that, under some circumstances, electrons might stop behaving as individuals and collide so often that they actually begin to flow like a viscous fluid with all kinds of unique properties.
But it was only last year that researchers confirmed the phenomenon, showing for the first time that, even at room temperature, electrons within graphene could act as a fluid 100 times more viscous than honey – something the researchers referred to as “quantum weirdness arising from [electrons’] collective motion“.
Now the same team, led by Sir Andre Geim – the University of Manchester physicist who won the 2010 Nobel Prize for his work characterising graphene – has shown that this liquid electron phenomenon is even crazier than we thought.
