Abstract: The results of a study of composite structures p-(Ag2O-Hg1−xCdxTe (x ~ 0.223)) based on nanosized silver oxide inclusions in a semiconductor matrix are presented. The HgCdTe layers were implanted with Ag+ silver ions. The modification was carried out by oblique (θ = 45°, 30°) ion bombardment. The morphology of the (111) Hg1−xCdxTe (x ~ 0.223) surface of epitaxial layers was studied under ion irradiation with an energy of 140 keV and a flux density of 4.8 × 1013 cm−2 at T = 300 K by atomic force microscopy. The low-temperature photoluminescence, Raman scattering, surface photovoltage, and impedance spectroscopy techniques were also used. The results of impedance spectroscopy showed the passive inductive properties of the composite structures investigated. The surface photovoltage investigation indicates that the ion-synthesized Ag2O/Hg(Cd)Te composite system can be a candidate for a multispectral (IR and sub-THz) detection system. A new mechanism for sub-THz detected by a synthesized semiconductor composite structure in which the metamaterial absorber is integrated directly into the MWIR semiconductor is presented. The photonic properties of the synthesized composite are discussed in the frame of the "antenna efficiency" paradigm based on using a metamaterial unit cell with the functions of a parasitic resonant element in the near field of the electrical small antennas. It is assumed that the nanostructured surface with silver inclusions plays a role of a small metamaterial-inspired resonant near-field parasitic antenna. [ABSTRACT FROM AUTHOR]
