| Popis: | In this paper, thermal transport properties study of partially amorphous porous silicon obtained by irradiation with swift (110 MeV) uranium ions is reported. A photoacoustic technique allows thermal conductivity evaluation of the samples with enhanced amorphous fraction (>80%). In particular, 3-fold thermal conductivity decrease is shown to be achieved for the completely amorphous porous silicon layers in comparison with as-prepared non-irradiated porous samples. |
