Nanoscale mechanical sensing at ambient conditions*

Negative charge nitrogen vacancy center in diamond (NV center) has attracted huge interest due to its unique spin properties even at room temperature. Its spin state could be optically addressed, manipulated and readout with excellent photo stability. Meanwhile, NV center is sensitive to many parameters, such as magnetic field, strain, and temperature, which opens up many applications ranging from magnetometry, temperature sensing to nanoscale NMR spectroscopy. In this talk we will discuss the application of diamond NV centers in nanoscale mechanical sensing at ambient conditions.
