Abstract
A nanoscale temperature detector including a diamond sensing probe with a transverse dimension of at least 200 nanometres and a sensing tip-having a curvature radius of less than 100 nanometres, less than 10 nanometres or less than 1 nanometre, and a plurality of colour centres, whose emission count rate show temperature-sensitive features. The diamond sensing probe has a transverse dimension of at least 200 nanometres and is connected to a to a detector system by means of a mounting structure. A thermal isolation barrier thermally decouples the sensing probe from the detector system.

A nanoscale temperature detector comprising
- a diamond sensing probe with a sensing tip having a curvature radius (R) of less than 100 nanometres, or less than 10 nanometres, or less than 1 nanometre, and comprising up to 100 ppm colour centres, whose emission count rate show temperature-sensitive features,
- wherein the diamond sensing probe is configured to optically guide a light emitted by the colour centres,
- wherein the diamond sensing probe has a transverse dimension of at least 200 nanometres, the nanoscale temperature detector further comprising
- a mounting structure connectable to a detector system, and
- a thermal isolation barrier thermally decoupling the sensing probe from said detector system.
