Band offsets, dielectric dispersion and some applications of CdSe/GeO2 heterojunctions
Khusayfan, Najla M.; Qasrawi, Atef; Alharbi, S. R.; Khanfar, Hazem K.; Kayed, T. S. (Elsevier GmbH, 2021)Herein, the formation, structural, morphological, compositional, optical, dielectric, photoelectrical and electrical properties of the CdSe/GeO2 heterojunctions are explored. While the surface displayed formation of deficient ... -
Design and characterization of ZnSe/GeO2 heterojunctions as bandstop filters and negative capacitance devices
AlGarni, Sabah E.; Qasrawi, A. F.; Khusayfan, Najla M. (Wiley-VCH Verlag, 2021)Herein, polycrystalline films of ZnSe which are coated onto Au substrates and recoated with amorphous layers of GeO2 are used as active material to perform as bandstop filters. The stacked layers of Au/ZnSe/GeO2 are coated ... -
Effects of polycrystalline GeO2 substrates on the structural, optical and electrical properties of ZnSe thin films
AlGarni, Sabah E.; Qasrawi, A. F.; Khusayfan, Najla M. (IOPScience, 2021)Herein, the effects of polycrystalline germanium dioxide substrates on the structural, morphological, optical and electrical properties of zinc selenide thin films are reported. Thin films of ZnSe coated onto GeO2 are ... -
Enhanced Optical and Electrical Interactions at the Pt/MgSe Interfaces Designed for 6G Communication Technology
Algarni, Sabah E.; Qasrawi, A. F.; Khusayfan, Najla M. (Wiley, 2022)Magnesium selenide thin films are coated onto glass and semitransparent Ptsubstrates (nanosheets) by the vacuum evaporation technique under avacuum pressure of 10−5mbar. The effect of Pt nanosheets of thicknesses of100 nm ... -
Hydraulic pressure and temperature efects on the structural, morphological and electrical properties of SeO2 powders
Algarni, Sabah E.; Qasrawi, A. F.; Khusayfan, Najla M. (Springer Link, 2022)Herein, powders of SeO2 are subjected to hydraulic pressure in the range of 1.0–12 MPa and heating cycles in the range of 290–383 K. The pressure and temperature effects on the crystalline nature, plane orientations, ...
