Abstract
Permittivity measurements at a microwave frequency 24 GHz have been made on n-type EuSe at low temperatures 4.2–77 K after various annealing times. Consideration of different models for annealing dependent permittivity leads to the polarizability of Se vacancy defects as the most likely explanation. Donor polarizability αd = 3.2 × 106 Å3is found and further an estimation for electron effective mass m∗ = 0.28m0.
