Black phosphorus could spur the next wave of tiny transistors (2015)
&gt;&quot;Graphene is a one-atom thick material with high electrical conductivity, but as a zero bandgap semiconductor, it acts like a metal. This means that transistors made of the material cannot be easily turned on and off.<p>Black phosphorus also can be separated into one-atom thick layers known as phosphorene. Unlike graphene, phosphorene acts as a semiconductor that can easily be switched on and off.&quot;<p>Disclaimer: I don&#x27;t know if Graphene does or doesn&#x27;t make a good semiconductor, but I think it&#x27;s interesting to have alternatives to Silicon other than GaAs or Graphene, and Phosphorene, if the claims turn out to be true, could very well be one such alternative...
