In the future, your cell phone calls and television pictures could become a lot clearer thanks to tiny antennas thousands of times smaller than the width of a human hair. At least thats the speculation of a University of Southern California researcher who has been investigating nanotube transistors.
The USC scientist, Bart Kosko, Ph.D., a professor in the schools Electrical Engineering Department, led a study that has demonstrated for the first time that minuscule antennas, in the form of carbon nanotube transistors, can dramatically enhance the processing of electrical signals, a development that could pave the way for improved performance of consumer electronic devices.
The finding adds to a growing number of promising electronic components that are nanotube-based, including logic gates for computers and diodes for light displays. The study appears in the December issue of Nano Letters, a monthly peer-reviewed publication of the American Chemical Society, the worlds largest scientific society.
