Research Topics


The proposed effort seeks to develop a technology for manufacturing radiation detectors from semiconductor quantum wire arrays. The approach is based on low cost non-aqueous electrodeposition into self-organized nanotemplates, followed by the incorporation of the array into micromachined detector. Dimensional precision at the nanometer scale of these materials ensures ultraprecision of parameters, as well as confinement of the electrical and electronic properties of these materials, which, in part, enables performance in high frequency range, and can overcome well known limitations of conventional II-VI sensors. The Phase I will demonstrate the proof-of-concept. Phase 11 will optimize the technology, build and test quantum array radiation detector prototypes. Phase III will commercialize the technology. BENEFITS: Proposed quantum array material can potentially enable new levels of performance and functionality of radiation detectors. Potential applications include light meters, smoke detectors, intruder alarms, street lighting switches, and other optoelectronic devices. The effort will also provide a foundation for a new generation of radiation detectors from -radiation to IR.
