High precision nano scale temperature sensing using single defects in diamond

Understand

Measuring local temperature with a spatial resolution on the order of a few nanometers has a wide range of applications from semiconductor industry over material to life sciences.

• When combined with precision temperature measurement it promises to give excess to small temperature changes caused e.g.
• by chemical reactions or biochemical processes.
• However, nanoscale temperature measurements and precision have excluded each other so far owing to the physical processes used for temperature measurement of limited stability of nanoscale probes.
