Microwave annealing of defects in ferroelectric triglycine sulfate

The effect of microwave irradiation of ferroelectric triglycine sulfate (TGS) samples with different degrees of imperfection (determined by the annealing conditions) has been investigated. It is shown that the irradiation effect depends on both the degree of perfection of the samples and the irradiation time (dose). As for gamma irradiation, low doses of microwave radiation lead to partial annealing of defects and, therefore, should improve the parameters of TGS-based devices. High irradiation doses cause degradation of TGS properties, which is highest in perfect crystals.
