"RADIATION RESILIENCE IN REDUCED DIMENSIONALITY SYSTEMS"
Space-based electronic systems such as communications satellites and interplanetary space probes have become increasingly
important since their inception in the mid 20th
century. However, as these systems become smaller and more sophisticated, the
ability to carry radiation shielding to protect against the space radiation environment becomes more difficult. Therefore, new
lightweight, radiation resilient electronics are needed to meet the demands of new probe designs. Current silicon based
transistors rely on charged separated regions prone to radiation, which can disrupt normal operation. Novel nanomaterials that
may be inherently radiation resilient offer promising alternatives. Recent research suggests that nanomaterials and nanomaterial
based electronic devices may have inherent radiation resiliency due to their reduced dimensionalities, and in some cases
enhanced self-healing due to their nanoscale sizes.
