Materials and Process Development for Ultraviolet Detector Technologies
All applications must be submitted in Zintellect
Description:
This project involves the development of new technologies for ultraviolet (UV) instrumentation and systems. Successful candidates will utilize thin-film processing and nanoscale interface engineering methods to fabricate advanced detector technologies and optical components. Research within the UV detector technology team has largely focused on the use of molecular beam epitaxy (MBE) for band structure engineering and passivation of silicon-based photodetectors [1, 2]. Developments in recent years has been geared toward wafer-scale processing as well as improving the space worthiness of MBE-passivated detectors. We also use atomic layer deposition (ALD) processes in order to engineer new coatings for advanced optics or detectors, including the customization of detector response over a broad wavelength range. The performance objectives for our technologies are defined to meet the objectives of a variety of NASA research programs with the ultimate goal of flight instrument and mission infusion. Participation in this research could include work on the development and evaluation of new MBE and ALD processes as well as other methods to improve detector performance and capabilities. During their NPP tenure the Fellow will be expected to report research/technology developments through publication of first-author manuscripts, conference presentations and proceedings, and in internal team meetings and seminars
