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…

Sub-second Temporal Magnetic Field Microscopy Using Quantum Defects in Diamond
Madhur Parashar, Anuj Bathla, Dasika Shishir +3
Wide field-of-view magnetic field microscopy has been realised by probing shifts in optically detected magnetic resonance (ODMR) spectrum of Nitrogen Vacancy (NV) defect centers in…
