Photoemission Study of the Electronic Structure of Zinc-Blende Manganese Telluride (ZB–MnTe)
Here we report the electronic structure of Zinc-Blende Manganese Telluride (ZB–MnTe). The theoretical photoemission (PES) spectrum at = hω 21.2 eV shows three distinct structure peaking at about –3.2 eV, –9.2 eV and –15.2 eV. On increasing the photon energy to 40.8 eV, the peak at –3.2 eV decreases in intensity, the peak at –9.2 eV becomes a prominent peak and the peak at –15.2 eV a broad structure. On the basis of the results of band structure calculation, these structures are interpreted to be associated with the density of states features. The peak at –3.2 eV arises from X 3 at –3.2 eV. The peak at –9.2 eV arises from L 1 at –5.5 eV and the peak at –15.2 eV arises from X 1 at –11.6 eV. Peak at –3.2 eV and at –9.2 eV are separated by an energy gap (or energy level difference) of –6.0 eV and peak at –9.2 eV and at –15.2 eV are separated by an energy gap or (energy level difference) of –6.0 eV. Finally, the energy gap (or energy level difference) between two peaks for ZB–MnTe fell within the range –0.5 eV to –7.5 eV indicating that it could be used for the development of solid-state devices such as blue light emitting diodes, lasers, solar cells and micro-wave.
