Effect of Ga substitution for In in LiInSe2 crystals on carrier transport behaviors and alpha particles detection

Thermal neutron detection with lithium-based semiconductors

“…As listed in Table 1, 6 Li-containing semiconductors in the presence of thermal neutrons, go through the 6 Li(n,α) 3 H reaction which produces charged particles. The phenomenon is illustrated in Figure 1 for the 6 Li-containing semiconductor detectors.…”

“…There is a critical need for better neutron detection technology that can replace the 3 He tubes, which are currently in short supply. Researchers are often limited by the capabilities of existing detector technologies to address the limited availability of 3 He gas.…”

“…There is a critical need for better neutron detection technology that can replace the 3 He tubes, which are currently in short supply. Researchers are often limited by the capabilities of existing detector technologies to address the limited availability of 3 He gas. On the other hand, in radioisotope identification devices to date, neutron detection has been achieved primarily using 3 He tubes.…”

“…Researchers are often limited by the capabilities of existing detector technologies to address the limited availability of 3 He gas. On the other hand, in radioisotope identification devices to date, neutron detection has been achieved primarily using 3 He tubes. In recent years the availability of this gas has become limited.…”

“…Since neutrons are electrically neutral their detection can be difficult. However, since certain isotopes such as 3 He, 6 Li, 10 B, and 157 Gd have large cross sections for thermal neutron absorption, useful neutron detectors can be developed by incorporating these isotopes as constituents. Each absorption (followed by a reaction) is characterized by a cross-section, a Q-value, and the reaction products, as shown in Table 1.…”
