Abstract

Abstract : The synthesis of CdTe nanocrystals (NCs) is performed by electrochemical deposition into prepared ion tracks in a a‐SiO2 /Si‐n template. As a result, CdTe NCs are obtained in a wurtzite (WZ) crystal phase. The measurement of the current–voltage characteristics shows that the CdTe (WZ NC)/SiO2 /Si system obtained in this way has n‐type conductivity. Computer simulations using the CRYSTAL computer code show good agreement between experimental and calculated lattice parameters. The theoretical calculations also show that the crystal has a direct bandgap at the Γ point of the Brillouin zone. Abstract : Herein, the electrochemical deposition synthesis of CdTe nanocrystals (NCs) into latent ion tracks in a a‐SiO2 /Si‐n template formed by 200 MeV Xe irradiation is demonstrated. As the result, CdTe NCs are obtained in a wurtzite (WZ) crystal phase. The of the current–voltage characteristics shows that the obtained CdTe WZ‐structured NCs in a a‐SiO2 /Si ion‐track template has n‐type conductivity.
