What Does PPES Stand For?

PPES stands for Photopyroelectric Spectroscopy

PPES, or Photopyroelectric Spectroscopy, is an analytical technique that combines photothermal and pyroelectric methods to investigate the thermal properties and structural characteristics of materials. By measuring the thermal response of a sample upon light excitation, PPES provides insights into absorptivity, thermal conductivity, and specific heat, making it valuable for material science, chemistry, and nanotechnology applications. This non-destructive technique is particularly effective for assessing complex materials and interfaces.
