Non-Destructive Evaluation of Irradiated Single walled carbon nanotube

Semiconductors have been used in electronics for decades and are an integral part of every circuit. Because of this, evaluating semiconductor performance and tolerance in different environments is crucial. For example, evaluating a semiconductor’s radiation tolerance can be quite useful such as for the radiation detectors in the Large Hadron Collider and for the solar panels on the international space station which are exposed to lots of radiation. Unfortunately, it is still unsure how radiation affects semiconductors, for this reason the student (Nicholas Dallaire) will study the tolerance of single walled carbon nanotube semiconductors. Nicholas will use transient grating spectroscopy (TGS) to evaluate the degradation of the semiconductors which have been exposed to radiation. TGS is a method used to characterize the surfaces of materials in a nondestructive way to determine a material’s elasticity, energy dissipation, thermal diffusivity. The research done will aid in figuring how semiconductors are affected by radiation and help innovate novel circuits which may need protection from radiation, such as satellites.
