"overcoming Boltzmann tyranny: silicon semiconductor limits prevent transistors from operating below certain voltage, by leveraging quantum mechanics... 3D transistor using ultrathin semiconductors with vertical nanowires operating efficiently at low voltages... potential to replace silicon... semiconductors: gallium antimonide, indium arsenide, leveraging quantum tunneling transistors encouraging electrons to push through (not over) energy barrier... performs 20X better than similar tunneling transistors"
