| Vertical Graphene Transistor |
Graphene is highly conducting and thus ideal for electronic applications. However, its extreme conductivity can also be a problem because devices made from the material remain conducting even when switched off. Researchers at the University of Manchester have now taken a step forward in overcoming this problem by making a new type of transistor from graphene that contains layers of boron nitride or molybdenum disulphide sandwiched between graphene sheets. The layers act as vertical tunnelling barriers that minimize current leakage – even at room temperature.
