The optical and electrical properties of MnTe films were investigated to ascertain the feasibility of their use in solar cell applications. Three ¡-MnTe thin films with different composition, i.e., Mn-47.9 at% Te, Mn-49.2 at% Te, and Mn-50.4 at% Te, were prepared using RF magnetron sputtering. All the films demonstrated a high light absorption coefficient (0.2 © 10 5 0.8 © 10 6 cm ¹1) and an optimal indirect band gap (1.37 1.52 eV) for solar cell applications. Furthermore, all of them exhibited p-type conductivity, with the Mn-47.9 at% Te film demonstrating three to four times higher carrier mobility (5.2 cm 2 •V ¹1 •s ¹1) than the Mn-50.4 at% Te film (1.6 cm 2 •V ¹1 •s ¹1).

The electronic structure of the (Ge,Mn)Te diluted magnetic semiconductors was investigated theoretically from first principles, using the fully relativistic Dirac linear muffin-tin orbital (LMTO) band structure method. The electronic structure is obtained with the local spin-density approximation (LSDA) as well as the LSDA+U method. The x-ray magnetic circular dichroism (XMCD) spectra of (Ge,Mn)Te DMSs at the Mn L 2,3 edges are investigated theoretically from first principles. The origin of the XMCD spectra in the compound is examined. The calculated results are compared with available experimental data.

Phys. 98, 063523 (2005);Motivated by the experimental synthesis of bulk MnTe with rocksalt structure, we use the first-principles calculations to explore the structural, electronic, and magnetic properties of VTe in four different phases: rocksalt, zinc-blende, wurtzite, and ground-state NiAs. It is found that the ground-state NiAs phase is antiferromagnetic, but both the zinc-blende and wurtzite phases exhibit truly half-metallic ferromagnetism, and the rocksalt phase is a nearly half-metal. Importantly, the rocksalt phase is energetically more stable than the zinc-blende and wurtzite ones. We further reveal that there is an interesting transition from the nearly half-metallicity in bulk rocksalt VTe to the truly half-metallicity at the Te-terminated (111) surface, and the Te-terminated (111) surface is energetically more stable than the V-terminated (111) surface, which makes VTe with rocksalt structure promising candidate for spintronic applications.
