“…The film was amorphous when the irradiation fluence was 5 × 10 12 n cm −2 . Bao et al 19 reported that the damage of 3 MeV Kr ion irradiation to CdZnTe crystals is greater than that of 2.08 GeV Kr ion irradiation because of a higher proportion of nuclear energy deposition. However, the affecting mechanism of heavy ion irradiation damage on the electrical properties in CdZnTe crystals is still controversial.…”

“…Currently, in world practice, silicon detectors, and germanium detectors are mainly used [1,2] to detect charged particles, also for a long period of time, other detectors have been used including cadmium telluride (CdTe) and gallium arsenide (GaAs-detectors) [3][4][5], as well as CdZnTe [6,7] for similar purposes.…”

In this work, we show a new method for obtaining silicon-lithium semiconductor structures using the bilateral drift of lithium particles into silicon mono-crystal in order to create nuclear radiation detectors with a wide bandgap. This method describes the simultaneous distribution of lithium ions on surfaces of cylindrical silicon crystals, which speeds up the process of obtaining the required detector structure. Here in this work, we aimed to identify the most optimal regimes of the electric field applied in the process of bilateral ion drift, as well as to investigate the effect of the thermal factors to create a drift of lithium ions. We can estimate these optimal regimes of voltage and temperature by making theoretical assumptions based on the numerical method for solving the Poisson continuity equation, the calculations of Pell and Louber. At the same time, simplifications were made to neglect the internal interaction of particles. The paper shows the results of modeling the process of bilateral drift under the influence of a stepwise increase in temperature and reverse voltage. This bilateral drift procedure facilitates the fabrication of silicon-lithium nuclear radiation detectors with large diameters and sensitive areas.

“…The process of irradiation might induce the displacement of atoms or electron defects which include the changes in the valence state of network atoms, modifier, or impurity atoms. Moreover, the changes in the glow curve shape can be used to deduce the damage created by the high radiation to the thermoluminescent material [26]. The extent of disordering in glass network can be deduced from Urbach energy (Urbach tail) which described the localized states present in the bandgap [27].…”

Different types of ceramics and glass have been extensively investigated due to their application in brachytherapy, radiotherapy, nuclear medicine diagnosis, radioisotope power systems, radiation processing of food, geological and archaeological dating methods. This review collects the newest experimental results on the thermoluminescent (TL) properties of crystalline and glassy materials. The comparison of the physico-chemical properties shows that glassy materials could be a promising alternative for dosimetry purposes. Furthermore, the controlled process of crystallization can enhance the thermoluminescent properties of glasses. On the other hand, the article presents information on the ranges of the linear response to the dose of ionizing radiation and on the temperature positions of the thermoluminescent peaks depending on the doping concentration with rare-earth elements for crystalline and glassy materials. Additionally, the stability of dosimetric information storage (fading) and the optimal concentration of admixtures that cause the highest thermoluminescent response for a given type of the material are characterized. The influence of modifiers addition, i.e., rare-earth elements on the spectral properties of borate and phosphate glasses is described.
