Description
This fellowship opportunity at the Naval Research Laboratory (NRL) focuses on advancing infrared imaging technology through the development of antimonide-based infrared alloys and Type II superlattices. The research aims to improve device performance by optimizing bandstructure for high quantum efficiency and low dark current, minimizing surface leakage via advanced device architectures and fabrication techniques, and enhancing material growth and process control to reduce costs and improve manufacturability.
Key research areas include:
- Design and simulation of infrared alloys, superlattices, and complete device structures.
- Growth of strained materials and device structures using molecular beam epitaxy.
- Structural characterization to analyze layer structure, composition, interfaces, and defects.
- Electronic characterization to measure carrier density, mobility, minority carrier lifetime, and trap levels.
- Advanced device fabrication techniques such as dry-etch and atomic layer deposition to create small pixel architectures with high uniformity and low surface damage.
- Design and fabrication of plasmonic structures to enhance infrared radiation coupling, increasing sensor quantum efficiency and enabling functionalities like tunable spectral or polarization selectivity.
This program is ideal for postdoctoral researchers interested in materials science, electronics, optics, and device physics related to infrared photodetection and focal plane array technologies.
