摘要：
The current-voltage characteristics of EuGa2S4<Co> single crystals were measured from 80 to 300 K with the aim of elucidating the mechanism of electrical transport. The results, interpreted as evidence of space-charge-limited currents with an exponential distribution of trap energies, were used to determine the trap depth (E-t = 0.30 eV), trap concentration (N-t = 4 x 10(13) cm(-3)), Fermi energy (E-F = 0.51 eV), equilibrium carrier concentration (p(0) = 9 x 10(9) cm(-3)), contact potential difference (Delta(phi) = 0.43 eV), and shift of the Fermi level (DeltaE(F) = 0.09 eV).
