Developments on Thermometric Techniques in Probing Micro- and Nano-heat
Abstract
Temperature is always of fundamental importance in various microscopic systems ranging from solid state nano-devices physics, chemical micro-reactions and biological cells. As traditional thermometers for macroscopic systems are not applicable in microscopic systems, alternative tools have to be developed to measure temperature at micro- and nano-scale. We provide here are view of the main currently available micro- and nano-thermometry tools including microscopic infrared thermometer, thermoreflectance, micro-Raman, plasmon energy expansion thermometry (PEET), Diamond thermometers, nanomaterial-based nanothermometers and two thermometric techniques based on scanning probe microscope (SPM), namely, scanning thermal microscope (SThM) and our recently-developed scanning noise microscope at terahertz (SNoiM).
