Improvement of the IR detectors by plasmon resonance using transparent nanoparticles obtained by the colloid dispersion synthesis (Overview)

摘要

HgCdTe crystals are very important semiconductors for the realization of infrared (IR) detectors, and as a rule an optimal response range is usually expected by controlling the exact balance of the ternary compound. Two approaches are available for the synthesis of HgCdTe semiconductors. The first is the well-known alloy process, in which the bandgap is tailored by varying the mole fraction x of CdTe in an Hg_(1-x)Cd_xTe alloy. The second is a superlattice structure, in which the bandgap is determined by the relative thicknesses of alternating HgTe and CdTe layers in a composite semiconductor. This Overview concerns colloidal synthesis, which is used as a new technology for obtaining new plasmon materials -transparent self-assembled conductive Ag_2O, Ag, graphene oxides in the production of plasmon material based on HgCdTe (MCT). In general, the results will be used to create multi-range HgCdTe detectors based on the plasmon resonance effect.
