Scanning thermal microscope

Scanning thermal microscopy (SThM) is a type of scanning probe microscopy that maps the local temperature and thermal conductivity of an interface. The probe in a scanning thermal microscope is sensitive to local temperatures – providing a nano-scale thermometer. Thermal measurements at the nanometer … See more SThM allows thermal measurements at the nano-scale. These measurements can include: temperature, thermal properties of materials, thermal conductivity, heat capacity, glass transition temperature, latent heat See more SThM requires the use of specialized probes. There are two types of thermal probes: Thermocouple probes where the probe temperature is monitored by a thermocouple junction at the probe tip and resistive or bolometer probes where the probe temperature … See more • SThM tutorial • SThM-FMR technique • SThM designs See more WebDec 7, 2001 · We review recent advances in experimental methods for high spatial-resolution and high time-resolution thermometry, and the application of these and related methods for measurements of thermal transport in low-dimensional structures.
