Question 1

What is TSDC and what does it reveal?

Accepted Answer

Thermally Stimulated Depolarization Current (TSDC) measures the current generated as a polarized sample is heated. It reveals dipole relaxation, space charge traps, and phase transition dynamics.

Question 2

What is the current detection resolution of the system?

Accepted Answer

It features an ultra-sensitive electrometer capable of resolving currents at the pico-ampere (pA) or femto-ampere (fA) level.

Question 3

What is the temperature range for pyroelectric testing?

Accepted Answer

Tests are typically performed from cryogenic temperatures (-150°C) up to high temperatures of 450°C or 1000°C with highly stable heating rates.

Question 4

Does it require sample metallization?

Accepted Answer

Yes, samples must be coated with electrode layers (such as gold or silver) on both major surfaces to collect the charge/current properly.

Question 5

Can it calculate the pyroelectric coefficient automatically?

Accepted Answer

Yes, the integrated software integrates the current-time curve over temperature to calculate polarization changes and the pyroelectric coefficient automatically.
