Enhanced Mid-Wave Infrared Absorption of HgCdTe (MCT) via Integration of Plasmonic Metal Oxide Nanostructure

Nagendrababu Vanamala, Tennessee State University


Mercury Cadmium Telluride (MCT) is the premier active material used in infrared (IR) detection technology. The most recent work related to the improvement of MCT-based detectors are associated with reducing the s/n ratio, and increasing the operating temperature without compromising performance. However, little has been done in manipulating the Electric field intensity near the absorber region of the device. The numerical studies show that the absorption profile in the mid-infrared can be enhanced by integrating metal oxide nanostructures. And also focuses on the geometrical parameterization and optimization of ITO nanostructure arrays. Simulated several types geometries, their corresponding effective absorption profiles, E-field distribution, and optimal geometric parameters. This work may improve the dynamic range and sensitivity of infrared detectors capable of operating in multiple detection windows. This work also may lead to improved light collection and absorption edge engineering, as MCT continues to be the material of choice in IR detection architectures. This Dissertation was written in Systems Engineering domain point of view in which has Conceptual Stage, Development Stage, Production Stage, Utilization stage, Support stage, Retirement stages (or operational, maintenance and disposal stages respectively).
