Magneto-Optical Confocal Microscope for Exploring Opto-Electronic Nanomaterial Hybrids and Heterostructures

This DURIP proposal seeks funding to acquire a cryogenic magneto-optical confocal microscope that will combine low-temperature, high-magnetic fields, and high-resolution microscopy for exploring nano-scale materials and heterostructures. The scientific objective of this equipment acquisition is to establish a state-of-the-art experimental optics capability at Northwestern University for understanding hybrid materials with tailored properties emerging from the combination of low-dimensional electronic systems with distinct characteristics arising from symmetry, structure, or external control. The proposed instrumentation will enable application of a wide range of optical and electronic environments and stimuli, allowing simultaneous exploration of the magnetic, optical, superconducting, and structural properties emerging in hybrid nanomaterials. It is anticipated that this new instrumentation will enable a long-term experimental program in characterization of highly customized nanoscale materials with unique and favorable properties for opto-electronics, thereby driving future quantum and nanoelectronics research broadly relevant to DoD research programs and initiatives. The flexibility, expandability, and wide feature set of the proposed equipment will contribute to the training of graduate and undergraduate students in nanoelectronics and optics techniques, helping to build a technical workforce with skills relevant to DoD scientific interests. The cryogen-free and low cost operation expands the impact of this apparatus to future experimental projects of any scale, including undergraduate training, representing a long-term investment in establishing a high-impact experimental facility.
