چکیده

We report on the lattice location of ion-implanted Cu in pand n-Si using the emission channeling technique. Following room-temperature implantation, the majority of Cu was found on near-substitutional sites in both pand n-Si. Annealing in the temperature range 200-600°C resulted in changes of near-substitutional Cu to random sites in p-Si, while in n-Si all of the near-substitutional Cu was converted to ideal substitutional lattice sites. The activation energy for dissociation is estimated to be 1.7-2.0 eV for near-substitutional Cu in p-Si and 2.9(2) eV for ideal substitutional Cu in n-Si.

Lattice location and stability of ion implanted Cu in Si

We report on the lattice location of ion implanted Cu in Si using the emission channeling technique. The angular distribution of beta(-) particles emitted by the radioactive isotope 67Cu was monitored following room temperature implantation into Si single crystals and annealing up to 600 degrees C. The majority of Cu was found close to substitutional sites, however, with a significant displacem...

Ultrasonic-assisted Method for Preparation of Cu-doped ZnS Nanoparticles in Water as a Highly Efficient Visible Light Photocatalyst

Ultrasonic-assisted method was applied for preparation of Cu+2-doped ZnS nanoparticles (mole fractions of Cu+2 ions are 0.000, 0.015, 0.030 and 0.060) in water as a template-free and green method at 30 min. The prepared nanoparticles were investigated by powder X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray (EDX) and UV–Vis diffuse reflectance spectra (DRS)...

Lattice location of implanted Ag in Si

The lattice location of implanted silver in Si was studied by means of the emission channeling technique. Following 60 keV room temperature implantation of radioactive Ag at a dose of 2-3×10 cm, we identify around 30% of Ag on near-substitutional sites (≈0.45 Å from ideal S-sites). Upon annealing at 200-300°C, the fraction on near-S sites reaches a maximum around 60-80%. For higher annealing te...

Lattice location and stability of implanted Cu in Ge

We report on emission channeling experiments using the radioactive isotope Cu implanted into single crystalline i-Ge at a dose of 2.4×10 cm. The lattice location of Cu was determined from the angulardependent β emission yield, which was measured by means of a position-sensitive detector around the <111>, <100> and <110> directions. We find that already in the as-implanted state a considerable f...

Correlation between crystal structure and optical properties of copper- doped ZnO thin films

ZnO and Cu doped[1] (CZO) thin films were prepared by radio frequency sputtering. The structural and optical properties of thin films were investigated using X-ray diffraction (XRD), atomic force microscopy (AFM), optical spectrophotometer, and photoluminescence (PL) techniques. ZnO thin films showed crystalline and micro-stress defects in the crystal lattice. Annealing of CZO thin films increa...
