Nanotube Transistors Give Hope to Better Space Electronics
U.S. Naval Research Laboratory electronics science and technology engineers have demonstrated the ability of single-walled carbon nanotube transistors (SWCNTs) to survive the harsh space environment. They are investigating the effects of ionizing radiation on the crystalline structures to aid the development of SWCNT-based nanoelectronics for use in harsh radiation environments.
"One of the primary challenges for space electronics is mitigating the susceptibility of prolonged exposure to radiation that exists in the charged particle belts that encircle Earth," says Cory Cress, materials research engineer. "These are the first controlled demonstrations showing little performance degradation and high tolerance to cumulative ionizing radiation exposure."
