Changes produced in thermoelectric materials by thermal-neutron irradiation

The effect of charged particle irradiation on the transport properties of bismuth chalcogenide topological insulators: a brief review

“…A few reports on light ion and electron irradiation in TI are discussed in this section. In addition to the charged species irradiation, carrier density tuning in Bi-chalcogenides has also been achieved through irradiation with species such as γ -rays 69 and thermal neutrons 70 mainly for the enhancement of the thermoelectric figure of merit.…”

Thermoelectric properties of high-performance n-type lead telluride measured insitu in a nuclear reactor core

“…The in-core irradiation effect on bulk thermoelectric materials like germanium telluride, silicon-germanium, etc. has been studied, [2][3][4][5][6] most under the comparatively low neutron uences of 10 13 to 10 19 n cm −2 . Neutron irradiation at relatively low temperatures (<200 C) created irradiation-induced point defects in these materials, reducing carrier mobility and lowering thermoelectric performance.…”

Tuning of the Thermoelectric Properties of Bi2Te3 Nanorods Using Helium Ion Irradiation

“…Date back to 1960s, the effect of various irradiation − viz., thermal neutrons, reactor radiations, protons, and inert gas ions on TE transport properties of Bi 2 Te 3 were extensively studied. The formation of defect clusters and dislocations in Bi 2 Te 3 by 7.5 MeV proton irradiation were observed .…”
