Current Project: NV-Center Quantum Sensing for Semiconductor Devices
Nanoscale quantum sensing is emerging as a powerful approach for characterizing advanced semiconductor devices. In this project, we develop ultrathin fluorescent nanodiamond (FND) films containing nitrogen-vacancy (NV) centers for mapping magnetic fields and temperature in semiconductor devices.
FNDs are electrically insulating carbon nanomaterials containing optically active NV centers. Their excellent photostability and distinctive quantum properties make them highly attractive for nanoscale Quantum Sensing.
The NV center has a well-defined spin-triplet ground state that can be optically probed through optically detected magnetic resonance (ODMR). The ODMR spectrum provides information about the local magnetic and thermal environment. Electrical currents flowing through a semiconductor device generate local magnetic fields, which can be detected by the Zeeman splitting of the NV center. By analyzing this splitting, we can quantitatively map the magnetic-field distribution of an operating device.
The NV resonance frequency is also highly sensitive to temperature. As the local temperature increases, the resonance frequency red-shifts. This temperature-dependent shift enables spatially resolved thermometry using the same FND sensing layer.
Hence, the ultrathin and uniform FND film, maintained proximity to the device surface, enables high-spatial-resolution simultaneous mapping of magnetic fields and temperature.
Research Goal
Our goal is to develop Diamond-based Quantum Sensing Platform for investigating the magnetic and thermal behavior of next-generation semiconductor devices.
