Fig. 3. TEM images of SiO2 nanoparticles at initial (a and b) and irradiated with neutron flux (c and d).TEM images shown in Fig. 3, have been taken up to ×1.200.000 magnification (10 nm index). From TEM images (Fig. 3a and b) of the initial nanoparticles it is seen that, all particles has 20 nm size in the samples. This shows that practically the process of “adhesion” does not occur in the initial sample without external influence. In other words, the experimental sample consists of pure nanoparticles, which has 20 nm particles diameter. Moreover, other two TEM images shown in Fig. 3c and d, we can say that new nanoparticles with about 70 nm size are generated in the sample by very little “adhesion” under the influence of neutron irradiation. And this small amount “adhesion” direct influence to electrophysical properties of nanomaterials [11], [12], [13], [14]. Furthermore, in order to study the lattice structure of SiO2 nanoparticles, it has been carried out SAED analyses for the samples exposed to neutron flux influence and initial circumstance in TEM device
