A comparative study is carried out for etching a surface with negative and positive ions, the results show completely opposite physical processes occur on silicon surface. Irradiation ions exhibits oxide removal, while irradiation shows an intense oxidation of sample Technology low-temperature ion cleaning electron-spectrometric control wafers has been developed. This technology shown that only...

We studied the possible correlations between defects and photoluminescence spectra in ZnO nanoparticles of sizes ranging from 43 nm to 73 nm in diameter. The defects and impurity contents were characterized by Fourier-transform infrared (FTIR) spectroscopy. The results show fewer carboxylate and hydroxyl impurities for particles of larger sizes. No significant variation in oxygen vacancy conten...

Conventional synthesis of new electrode materials, involving heat treatment in high-temperature furnaces, followed by materials characterization, is an extremely long process that can easily miss the best set of conditions for the synthesis of particular compounds. Consequently, it is important to develop in-situ techniques to directly observe changes in material structures and chemistry at the...

Low-temperature solution-processable vanadium oxide (V₂Ox) thin films have been employed as hole extraction layers (HELs) in polymer bulk heterojunction solar cells. V₂Ox films were fabricated in air by spin-coating vanadium(V) oxytriisopropoxide (s-V₂Ox) at room temperature without the need for further thermal annealing. The deposited vanadium(V) oxytriisopropoxide film undergoes hydrolysis in...

The influence of oxygen plasma treatments on the surface chemistry and electronic properties of unintentionally doped and Mg-doped In 2 O 3 (111) films grown by plasma-assisted molecular beam epitaxy or metal-organic chemical vapor deposition is studied by photoelectron spectroscopy. We evaluate the impact of semiconductor processing technology relevant treatments by an inductively coupled oxyg...
