Opis:
Monocrystalline films of zinc oxide were grown at 300C by atomic layer deposition. ZnO layers were grown on various substrates like ZnO bulk crystal, GaN, SiC and $Al_2O_3$. Electrical properties of the films depend on structural quality. Structural quality, surface morphology and optical properties of ZnO films were characterized using X-ray diffraction, scanning electron microscopy, and photoluminescence, respectively. High resolution X-ray diffraction spectra show that the rocking curve FWHM of the symmetrical 00.2 reflection equals to 0.058° and 0.009° for ZnO deposited on a gallium nitride template and a zinc oxide substrate, respectively. In low temperature photoluminescence sharp excitonic lines in the band-edge region with a FWHM equal to 4 meV, 5 meV and 6 meV, for zinc oxide deposited on gallium nitride, zinc oxide and sapphire substrate, respectively.

Opis:
The paper presents the results of characterization of MOS structures with aluminum oxide layer deposited by ALD method on silicon carbide substrates. The effect of the application of thin SiO2 buffer layer on the electrical properties of the MOS structures with Al2O3 layer has been examined. Critical electric field values at the level of 7.5–8 MV/cm were obtained. The use of 5 nm thick SiO2 buffer layer caused a decrease in the leakage current of the gate by more than two decade of magnitude. Evaluated density of trap states near the conduction band of silicon carbide in Al2O3/4H-SiC MOS is about of 1×1013 eV−1cm−2. In contrast, the density of the trap states in the Al2O3/SiO2/4H-SiC structure is lower about of one decade of magnitude i.e. 1×1012 eV−1cm−2. A remarkable change in the MOS structure is also a decrease of density of electron traps located deeply in the 4H-SiC conduction band below detection limit due to using of the SiO2 buffer layer.

Opis:
Ni/Si-based contact schemes based on the solid-phase regrowth process have been developed to form low-resistance ohmic contacts to GaN with a minimum contact resistivity of 1×10$\text{}^{-3}$ Ωcm$\text{}^{2}$ and ≈1×10$\text{}^{-2}$ Ωcm$\text{}^{2}$ to GaN:Si (n ≈ 2×10$\text{}^{17}$ cm$\text{}^{-3}$) and GaN:Mg (p ≈ 3×10$\text{}^{17}$ cm$\text{}^{-3}$). The solid-phase regrowth process responsible for the ohmic contact formation was studied using X-ray diffraction, secondary ion mass spectrometry and Rutherford backscattering spectrometry.

Opis:
Electrical properties of RF magnetron sputtered p-NiO films were characterized after fabrication and after gamma irradiations using $\text{}^{137}Cs$ and $\text{}^{60}Co$ sources. Electrical parameters are obtained from the Hall measurements, impedance spectroscopy and C-V measurement of n-Si/p-NiO junction diodes. The results show that resistivity of the NiO film is gradually increased following after sequential irradiation processes because of the decrease in holes' concentration. Hole concentration of a NiO film decreases from the original value of $4.36 \times 10^{16} cm^{-3}$ to $2.86 \times 10^{16} cm^{-3}$ after $\text{}^{137}Cs γ$ irradiation with doses of 10 Gy. In the case of γ irradiation from $\text{}^{60}Co$ source, hole concentration of the film decreases from $6.3 \times 10^{16}//cm^3$ to $4.1 \times 10^{16}//cm^3$ and to $2.9 \times 10^{16}//cm^3$ after successive expositions with a dose of 20 Gy.

Opis:
The electrical properties of the CdTe/ZnTe quantum dot system have been analyzed to identify deep-level defects related with the presence of quantum dots. The capacitance-voltage (C-V) and deep level transient spectroscopy measurements were used to investigate the samples. A reference ZnTe sample (without dots) was also studied for comparison. Both samples were grown by molecular beam epitaxy technique on the n-type GaAs substrate. The quantum dots were formed by a Zn-induced reorganization of a thin CdTe layer. The presence of quantum dot formation was confirmed by micro-photoluminescence measurements. The deep level transient spectra for both samples are complex. In order to characterize individual contributions to the deep level transient spectra the latter have been simulated by separated Gaussian components [1]. The results of the deep level transient spectroscopy measurements yield the conclusion that the same defects are present in both materials but there is an increased concentration of the defects in the quantum dot structures. No deep level associated directly with the quantum dot confinement has been identified.

The interaction between CdTe and In during the formation of an ohmic contact has been investigated. Emphasis is placed on the study of the effect of thermally induced sublimation of cadmium on electrical properties of contacts. Presented results prove the effectiveness of cap annealing and rapid thermal processing in fabrication of improved ohmic contacts with limited Cd losses during the contacting procedure.

Opis:
Interfacial reactions between GaSb and Au were studied by Rutherford backscattering, X-ray diffraction, and cross-sectional transmission electron microscopy. Evaluation of the extent to which the GaSb substrate decomposes was of primary concern. The results give evidence that the reaction takes place even at temperatures as low as 180°C. High reactivity of gold towards GaSb revealed by this study demonstrates that Au-based metallization is not a good candidate for device quality ohmic contacts to GaSb-based devices.
