Physicists at the University of Maryland have fabricated a semiconducting nanotube transistor that shows a mobility nearly 25% higher than any previous semiconducting material and >70 times higher than the silicon used in today's computer chips, mobility being a measure of how well as semi-conductor conducts electricity. The mobility reported exceeds 100,000 cm2 per volt-second at room temperature. To perform their measurements, the team prepared extremely long nanotubes (put o 0.3mm). The nanotubes were grown directly on flat silicon chips, and a special technique using a SEM was developed to locate the nanotubes on the chip so that wires could be connected to them.
