The stringent control of the epitaxial process was necessary for achieving the superlative performance and desiredstructures.

Results and discussion Raman measurements in Ga As 1-x Bi x (x = 1%, 2%, 3%) Quantum Well (QW) structures grown on (100) and (311)B Ga As substrates were performed to investigate the lattice vibration properties of the structures. more Results and discussion Raman measurements in Ga As 1-x Bi x (x = 1%, 2%, 3%) Quantum Well (QW) structures grown on (100) and (311)B Ga As substrates were performed to investigate the lattice vibration properties of the structures.

It is also seen that epitaxy is essential for realizing modern semiconductor device like Fin FETs.

The cheap and improved semiconductor structure like vertical MOSFET also required service of epitaxy technique.Consequently, KNN pellets with different K/Na ratios were sintered to 95% relative density in air and N 2 using a conventional mixed oxide route.Oxygen vacancies (V O ••) played a major role in the semi-conduction mechanism in low p(O 2) for all compositions.The values of ε and ε show a steep decline with increasing frequency and then reach a constant value at high frequency, whereas the increments of M and M with frequency are exponential. log f plot has a strong peak behaviour, especially in the accumulation region.These experimental results suggested that the Ru 0.03 −PVA interfacial layer could be used as a high dielectric material instead of conventional materials.Impedance spectro-scopy and thermo-power data confirmed KNN to be n-type in low p(O 2) in contradiction to previous reports of p-type behaviour.The best piezoelectric properties were observed for air-rather than N 2-sintered samples with d 33 = 125 p C/N and k p = 0.38 obtained for K 0.51 Na 0.49 Nb O 3 .Therefore, the modified ((ln I 0 T 2 − q 2 σ 2 s0 2k T 2 =ln (AA *) − q / 0 B0 k T) vs.(1 k T)) relation has been extracted from (I-V) characteristics, where the values of Φ B0 and A * Simul have been found in different temperature ranges.The obtained results have been compared to the existing experimental data and a good agreement was found.The obtained electrical results suggested that the complex dielectric constant (ε * = ε − jε), complex...more Ag/Ru 0.03 −PVA/n-Si structures were successfully prepared and their morphological and electrical properties were investigated.
