The composite samples of porous n-Si,
which have been prepared by anodic etching and embedded with Ni
and Co nanostructures by electroless process, were investigated by
null-ellipsometry technique. The ellipsometric data were analysed
in the multilayer model and the composition of porous layer on the
substrate surface was determined. The null-ellipsometry technique
was shown to be an efficient tool for nondestructive testing and
characterization of porous n-Si samples with embedded
transition metal structures.
Keywords: porous n-Si,
transition metal nanoparticles, null-ellipsometry

Nul-elipsometrijos metodu ištirti sudėtingosios
sandaros porėtieji n-Si dariniai, paruošti anodiniu
ėsdinimu, su Ni ir Co dalelėmis, įterptomis elektrocheminio
proceso būdu. Elipsometriniai duomenys išanalizuoti, pasinaudojant
daugiasluoksniu modeliu ir nustatytas porėtojo sluoksnio,
suformuoto padėklo paviršiuje, sąstatas. Gauti duomenys parodė,
kad nul-elipsometrija yra efektyvus neardantis būdas
charakterizuoti porėtojo n-Si darinius su įterptomis
pereinamųjų metalų dalelėmis.
