What Are the Challenges of Measuring Temperature at the Nanoscale?
Measuring temperature at the nanoscale presents several challenges:
1. Resolution: Traditional thermometers are too large to measure temperature at the nanoscale. Techniques like scanning thermal microscopy (SThM) and Raman spectroscopy are often used. 2. Accuracy: Ensuring accurate measurements is difficult due to the small size and high surface area-to-volume ratio of nanomaterials, which can lead to rapid heat dissipation. 3. Non-Contact Methods: Non-contact methods are preferred to avoid perturbing the system being measured. These include optical methods and electron microscopy-based techniques.
