Ag/SeO2/C avalanche type resonant tunneling schottky barriers
Al Garni, Sabah E.; Qasrawi, A. F.; Khusayfana, Najla M. (SciELO - Scientific Electronic Library Online, 2022)Herein, the design and characterization of Ag/SeO2/C avalanche type resonant tunneling devices are reported. Thin pellets of SeO2 nano-powders pressed under hydraulic pressure of 1.0 MPa which is used as the active material ... -
Growth and characterization of PbSe microcrystals via the pulsed laser welding technique
Alkhamisi, Manal M.; Khanfar, Hazem K.; Algarni, Sabah E.; Qasrawi, Atef Fayez (SPRINGER HEIDELBERG, 2022)Herein lead selenide crystals are fabricated by the pulsed laser welding (PLW) technique within 2 min. The effect of the pulse width on the crystallinity, surface morphology, structural parameters, compositional stoichiometry, ... -
Growth and characterization of vacuum evaporated MgSe thin films
Almotiri, R. A.; Qasrawi, A. F.; Al Garni, Sabah E. (Springer, 2022)Herein, thin flms of magnesium selenide are thermally grown in a vacuum deposition (VD) system onto glass substrates under a vacuum pressure of 10–5 mbar. The flms are structurally, morphologically, compositionally, and ... -
Lead selenide microcrystals fabricated by the pulsed laser welding technique employed as 6G technology microwave resonators and as MOS capacitors
Alkhamisi, Manal M.; Khanfar, Hazem K.; Qasrawi, A. F. (Elsevier, 2022)value larger than 100 GHz nominating the devices for 6G technology applications. Moreover, investigations on the current conduction mechanism have shown the preferred current conduction by quantum mechanical tunneling ... -
Properties of (Glass, Pb)/MgSe interfaces designed as terahertz band filters
Qasrawi, A. F.; Samen, Lara O. Abu; Atari, Samah S. (Springer, 2023)Herein, thin films of MgSe (300 nm) are deposited onto glass and semitransparent Pb (150 nm) substrates by the thermal evaporation technique under a vacuum pressure of 10−5 mbar. The films are structurally, morphologically, ... -
SeO2 microwires designed as low temperature abrupt microelectronic switches, negative resistance and negative dielectric constant sources
Qasrawi, A. F.; Ghannam, W. S. (John Wiley & Sons, Ltd, 2022)erein, the structural, morphological, compositional, and electrical properties of SeO2 microwires are studied and analyzed. Microwires of SeO2 of dimensions of 460×30×30 (μm)3 are electrically characterized in the temperature ...
