Since the invention of the transistor, silicon semiconductors have been king. But now silicon-based transistors are nearing the limit of their potential. Excess heat and manufacturing hurdles are impeding the development of ever-faster and smaller processors.
Advances in materials and chip design to resist extreme heat and move huge amounts of data, quickly, will be crucial. Experts are exploring three technologies to overcome these challenges: spintronics, graphene and memristors. They are what will someday make ultra-energy-efficient supercomputers small enough to fit anywhere -- even in the palm of your hand.
