Abstract

The relationships between the figure of merit R₀A representing the junction property and deep levels representing electric properties of semiconductors have been investigated. R₀A can be estimated by current-voltage (I- V) measurements. Deep levels can be estimated using spectral analysis of deep level transient spectroscopy (SADLTS). It has been confirmed that values of activation energies concentrate around 30 meV with the increase of R₀A. This suggests that the influence from the inherent deep levels in the HgCdTe device becomes strong due to the increase of R₀A, resulting in the improvement of the diode characteristics.
