Observation of Shear Strain in Ion-Implanted Diamond Substrate and Diamond Nanophotonic Structures
Ayan Majumder, Vivek K Shukla, Anuj Bathla +4
Negatively charged nitrogen-vacancy (NV) centers and other color centers in diamonds have emerged as promising platforms for quantum communication, quantum information processing,…
In-Substrate Imaging of Diamond hBN FET Current via Widefield Quantum Diamond Microscopy
Anuj Bathla, Subrat Kumar Pradhan, Ajit Kumar Dash +7
We demonstrate widefield magnetic imaging of current flow in hydrogen terminated diamond field effect transistors (FETs) through in-substrate nitrogen vacancy (NV) centers. Hydroge…
Dictionary-Based Reconstruction of Spatio-Temporal 3D Magnetic Field Images from Quantum Diamond Microscope
Anuj Bathla, Madhur Parashar, Matthew Markham +2
Three-dimensional magnetic imaging with high spatio-temporal resolution is critical for probing current paths in various systems, from biosensing to microelectronics. Conventional…
