In this article, the properties of the Ge/Bi 2 O 3 interfaces as microwave cavities are reported and discussed. The interface is composed of monoclinic Bi 2 O 3 films grown onto polycrystalline cubic Ge substrate. It is observed that consistent with the theoretical design of the energy band diagram, the experimental current-voltage characteristics of the Yb/Ge/Bi 2 O 3 /C hybrid device structure exhibits electronic switching property. In addition, the capacitance, resistance and microwave cutoff frequency spectral analysis in the frequency domain of 0.01-1.50 GHz revealed a frequency dependent tunability of the device. Moreover, while the Yb/Bi 2 O 3 /C interface displays negative capacitance effect, the Yb/ Ge/Bi 2 O 3 /C interfaces are also found to have the ability of altering the resistance up to three orders of magnitude. Such property allowed reaching a cut off frequency up to 116 GHz. The electronic features of the device indicated that the Ge/Bi 2 O 3 interfaces are attractive for production of negative capacitance field effect transistors and band pass/reject filters.

“…Even though different synthesis methods are available for bulk production with less impurity, spray pyrolysis is recommended as the most excellent method for the synthesis of nanocomposites, because it does not require any capping, or reducing agent. Ca, Zn, Ni, Mg, Cu, and Fe were the principal metals used in different applications …”

In this study, a distinctive hollow MgNi1.4Zn0.6/CaCu2.79Fe4.21O12 nanocomposite was synthesized for the first time using ultrasonic high‐temperature spray pyrolysis method controlled at 1200°C. Effect of various concentrations (0.01, 0.1, and 1 mol L−1) of the precursor solution on particle size and crystalline phase of nanocomposites was also analyzed. XRD and SEM results confirmed the difference in the particle size and crystalline pattern of the synthesized nanocomposite arisen due to the difference in concentrations. The results of antibacterial and antioxidant studies showed that the nanocomposites possessed remarkable antibacterial and antioxidant activities. Thus, the prepared hollow MgNi1.4Zn0.6/CaCu2.79Fe4.21O12 metal oxide nanocomposite via ultrasonic high‐temperature spray pyrolysis can be an excellent material in various biomedical applications.

“…Metals such as Zn, Cu, Ni, Fe, and Mg have applications in various elds including photo reactive devises, electrical, capacitance, photo degrading, and biomedical. [12][13][14][15][16] Thus, the unique distinctive properties of the metals led us to develop a nanocomposite with all ve metals. Hence, in the present study, we primarily focused on the production of the ve metal based nanocomposite using ultrasonication high temperature spray pyrolysis.…”
