Carbon Nanotubes for Radiation-Tolerant Electronics.

Electronics for space applications have stringent requirements on both performance and radiation tolerance. The constant exposure to cosmic radiation damages and eventually destroys electronics, limiting the lifespan of all space-bound missions. Thus, as space missions grow increasingly ambitious in distance away from Earth, and therefore time in space, the electronics driving them must likewise grow increasingly radiation-tolerant. In this work, we show how carbon nanotube (CNT) field-effect transistors (CNFETs), a leading candidate for energy-efficient electronics, can be strategically engineered to simultaneously realize a robust radiation-tolerant technology. We demonstrate radiation-tolerant CNFETs by leveraging both
