The semiconductor-electrolyte interface : Optical transitions in CdMnTe alloys - Lemasson, P.; Wu, B.-L.; Triboulet, R.; Gautron, J. (Elsevier)
The junction p-Cd"1"-"xMn"xTe-electrolyte is studied under monochromatic illumination for the alloy composition range 0 =〈 x =〈 0.7. Optical transitions in the semiconductor are evidenced by photocurrent measurements. In the composition range 0 =〈 x =〈 0.45, the nature of the fundamental transition appears to be the same as in CdTe (valence band Γ -〉 conduction band Γ ). For x 〉 0.45, the observed photocurrent pak, pinned at a constat energy value ca. 2.1 eV, may presumably be related to a transition Γ -〉 d(Mn) level whereas the photocurrent edge associated to the forme transition increases linearly with x.
