Swift ion irradiation effects on L-threonine amino acid single crystals

Single crystals of L-threonine were subjected to 50 MeV Li3+ ion irradiation at various ion fluences. Radiation induced changes in the structural, electrical, thermal and optical properties of the crystals have been studied in detail. The ion fluence dependence on these properties has also been discussed. Surface modifications in the crystals have been explored through atomic force microscopy. It has also been observed that the powder second-harmonic generation efficiency of irradiated L-threonine varies with the ion fluence studied.
