Multimodal correlative dislocation characterization - a system for optoelectronic and nanomechanical characterization and manipulation of 1D defects
Abstract
A system is proposed for enabling accelerated multi-modal correlated microscopy and spectroscopy of dislocations and their multifunctional properties (optical, electronic, magnetic, and mechanical). The integrated system will combine multiple pieces of scanning electron microscopy (SEM) based, atomic force microscopy (AFM) based, and dual-use instrumentation. Although the various instruments and components will themselves provide a range of valuable new experimental capabilities with applicability to a gamut of scientific research areas of importance to the Department of the Air Force (both Air Force and Space Force), when used together they will enable a novel multiscale, multimodal workflow for correlative optoelectronic and nanomechanical characterization of dislocations far beyond anything that currently exists at Ohio State University. The workflow enabled by the combination of instruments will make it possible to map out arrays of one-dimensional line defects (dislocations) that are ubiquitous in crystalline solids. Once identified the properties of dislocations will be measured using the SEM based imaging as a reference for electrical, magnetic, optical, and mechanical testing of arrays and even single dislocations. The system is designed specifically to enhance the experimental research of ongoing and recently funded AFOSR programs. These include FA9550-21-1-0278, Dislocations as nature s quantum wires, 2021-2025, the recently announced MURI Dislocations as interconnects for spin qubits, 2023-2028, and FA9550-22-1-0012, Center of Excellence in Radiation Effects in Electronic Materials, Devices, Circuits, and Systems .
