Journal ArticleDOI
Investigation of thin film of metal oxides on silicon with impedance spectroscopy
TL;DR: In this article, complex impedance spectroscopy has been used for investigation of MIS structures with thin metal oxide films of (Al 2 O 3 ) x (TiO 2 ) 1−x, which were deposited on Si substrates by spin-on-coating from sol solution and underwent additional thermal treatment.
Journal ArticleDOI
Nitrogen incorporation into GaAsN and InGaAsN layers grown by liquid-phase epitaxy
TL;DR: In this article, a comparison of nitrogen incorporation in GaAsN and InGaAsN layers grown on GaAs substrate from Ga- and In-rich solution, respectively, by liquid-phase epitaxy is presented.
Journal ArticleDOI
Influence of interface states on the write characteristics of MNOS memory structures
Journal ArticleDOI
Electrical properties of (Al2O3)x(TiO2)1-x films deposited on a silicon substrate
TL;DR: In this article, direct current conductance in Al/(Al2O3)X(TiO2)1-X/silicon structure was studied, the dielectric layers being deposited by the chemical solution deposition method.
