“…As for examples, the participation of silver ions in the structure of CdBr 2 is observed to enhance the light absorption in the crystals 5 . In another work, the phototreatment using bicolor coherent laser pulses of wavelengths of 1540 and 770 nm, it was possible to stimulate the linear electrooptical effects in CdBr 2 /Cu nanocomposites 6 . The application of CdBr 2 in many technological sectors other than communication technology, motivated us to explore its performance as an electronic device suitable for microwaves sensing.…”

Herein, cadmium bromide thin film devices are designed for possible use in communication technology. The 1.0 m µ thin layer of CdBr 2 is sandwiched between two Au (1.0 m µ thick) layers using the thermal evaporation technique under a vacuum pressure of 10 -5 mbar. The Au/CdBr 2 /Au devices are structurally morphologically and electrically characterized. It is observed that the hexagonal cadmium bromide exhibits large lattice mismatches with cubic Au substrates. The randomly distributed nanorod like grains is accompanied with average surface roughness of ~26 nm. When an ac signal of low amplitude is imposed between the terminals of the Au/CdBr 2 /Au devices, a negative capacitance effect in the frequency domain of 10-1800 MHz is observed. In addition, analysis of the impedance spectra in the same domain has shown that the device behaves as band pass/stop filters suitable for 4G technology. The microwave based standard analysis of the Au/CdBr 2 /Au band filters have shown that it displays a notch ( co f ) frequency of 2.0 GHz. The cutoff frequency at co f reaches 7.86 GHz. The features of the Au/CdBr 2 /Au devices nominate it for use as microwave resonators and as negative capacitance devices suitable for; 4G technology, noise reduction and for parasitic capacitance cancellation.
