Quantum Metrology

Maintaining hardware integrity of integrated chips (ICs) is crucial to reduce cyber vulnerabilities in military, financial, and government infrastructures. Hence, test & evaluation (T&E) techniques need to maintain a technological edge over the counterfeiting capabilities. This requires new non-destructive approaches to complement the capabilities of the present hardware verification methods. In two-dimensional (2D) semiconductors, the Coulombic field lines extend well outside the 2D material. As they bind an electron and a hole to form an exciton inside the 2D material, the external field lines induce excitons that are sensitive to the local energy and spatial distribution of the defects outside the 2D system.
