Dynamical Mechanical Analysis
Dynamical Mechanical Analysis (DMA)
In Material Property Analysis
please contact us for pricing

Dynamical mechanical analysis (DMA) is used to study changes in the mechanical properties of a material under periodic stress as the temperature is varied. DMA results are used to assess: glass transitions, melting points, elastic modulus, strain-to-break, toughness, creep, and numerous other thermal and mechanical properties.

Photoelectron Spectroscopy in Atmosphere
Photoelectron Spectroscopy in Atmosphere (PESA)
In Analytical Services,Material Testing
please contact us for pricing

Photoelectron Spectroscopy in Atmosphere (PESA) is a technique used to analyze the work function of a surface: i.e., the amount of energy needed to remove an electron from the sample. Work function is particularly important to measure as it can determine the efficiency and other key properties of junction contacts. It is a fundamental property for Schottky barrier devices used in many of our electronics. In addition to measuring the work function, PESA can also be used for certain samples to estimate the density of states (DoS), highest occupied molecular orbital (HOMO) energy level, lowest unoccupied molecular orbital (LUMO) energy level, band gap and energy gap.
