The biggest issue is that the substance only works in two dimensions, making it hard to use to build complex pieces of hardware. That’s why researchers from Oxford, Stanford and the Lawrence Berkeley National Laboratory are turning their attentions to Cadmium Arsenide. Like its more famous frenemy, the substance can transmit electricity at tremendous speeds, but will also work in three dimensions, which is far more useful when building transistors and sensors.
Researcher Yulin Chen goes so far as to say that this “family of materials could be a good candidate for everyday use.” It’s easy to make bold claims before the locked doors of a university lab, but still, if smartphones are ever going to make use of graphene in the real, three-dimensional world, then this could be the missing piece in the puzzle.
