..... Heat dissipation of transistors (and other switching devices) due to their necessarily limited thermodynamic efficiency, limits their density in circuits, since overheating can cause them to malfunction. This is likely to be a problem for any type of densely packed nanodevices [133] 141] [142]. Vanishing bulk properties and nonuniformity of doped semiconductors on small scales. This can only be overcome either by not doping at all (accumulating electrons purely using gates, as has been demonstrated in a GaAs heterostructure) 214] or by making the dopant atoms form a regular array. ....
