Inorganic Materials Aims and scope

Abstract

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 × 1013 cm–3), Fermi energy (E F = 0.51 eV), equilibrium carrier concentration (p 0 = 9 × 109 cm–3), contact potential difference (Δϕ = 0.43 eV), and shift of the Fermi level (ΔE F = 0.09 eV).
