Vorobets M. Influence of finishing chemical processing on formation and properties of porous silicon and cadmium telluride

This thesis explores the influence of Si-surface finishing chemical processing approaches on the both porous silicon formation process by anodization and its properties. It was shown, that processing in NH4OH:H2O2:H2O solution leads to micro- or mesoporous silicon layer formation, and in HNO3:H2O2:H2O or HCl:H2O2:H2O solution - macroporous silicon. The possibility of porous silicon formation in an evaporations of HF:C2H5OH:H2O was revealed. A way of porous silicon passive surface layer formation was proposed. For the first time porous CdTe was generated by anode dissolution of CdTe crystals in HNO3:HF:H2O or HNO3:HCl:H2O, and also electronic and optical properties of the generated porous layers were investigated.
