System for Research on Hot Optoelectronic Carrier Transport in Polar Insulators
Abstract
System for Research on Hot Optoelectronic CaPrincipal Investigator: Jonathan E. Spanier, Drexel University ONR Program Officer: 312 [Bennett, Brian R.] Funds are requested to acquire specialized magneto-optoelectronic instrumentation to enable research on the remarkable properties of light-activated electronic carriers in a subset of electrical insulators that are crystallographically polar. Materials to be studied are primarily in film form and produced by methods in which film crystallization is carried out separately from (following) its deposition, producing materials of atomic structure di?erent than those using other film methods, new film compounds, and films with improved scalability and at reduced cost. High electron mobility is a desirable property of semiconductors essential to faster and more efficient devices, e.g., switches, optical detectors, imagers; and exotic quantum phenomena is attractive for novel quantum computing paradigms, but these are hardly expected to exist in an electrical insulator, or dielectric. The system will permit study of a novel optically-generated high-mobility electronic phase that can be produced in insulating materials that lack a crystallographic center of inversion symmetry. The wide range of temperatures and tunable monochromatic light wavelength operability of the system will advance understanding and practical potential for technologies based on the so-called bulk photovoltaic e?ect. The instrumentation will enhance the quantity and quality of ongoing DoD-sponsored research and research-related education at Drexel University and with collaborators and student researchers at other academic institutions. The instrumentation as proposed, which is not known to exist elsewhere on campus or in the Philadelphia area, will be available to students and postdoctoral researchers from several research labs, to visiting students and scientists, and to DoD laboratory collaborators. The quoted cost of the proposed instrumentation, which consists of a widely-tunable quasi-continuous-wave laser source consisting of an integrated pump and optical parametric oscillator, electromagnet and closed-cycle cryostat, fully interfaced and integrated, is $199,094.rier Transport in Polar Insulators
