Structural and Electronic Properties of Chalcopyrite Semiconductors
We have studied the structural and electronic properties of pure, deffect and doped chalcopyrite semiconductors using Density functional theory (DFT) based first principle technique within Tight binding Linear Muffin Tin orbital (TB-LMTO) method. Our calculated structural parameters such as lattice constant, anion displacement parameter(u) in case of pure chalcopyrite and anion displacement par...
متن کاملChalcopyrite Nanoparticles as a Sustainable Thermoelectric Material
In this report, copper iron sulfide nanoparticles with various composition were synthesized by a thermolysis based wet chemical method. These inherently sustainable nanoparticles were then fully characterized in terms of composition, structure, and morphology, as well as for suitability as a thermoelectric material. The merits of the material preparation include a straightforward bulk material ...
متن کاملA study of energy gap, refractive index and electronic polarizability of ternary chalcopyrite semiconductors
A simple relation between the optical electronegativity, energy gap, refractive index and electronic polarizability is given for ternary chalcopyrite semiconductors. Energy gap has been evaluated from the optical electronegativity whereas refractive index and electronic polarizability values have been evaluated from the energy gap by proposing a linear relation between them. The calculated valu...
متن کاملTHE ROLE OF JAHN-TELLER EFFECT ON THE MAGNETIC PROPERTIES OF Fe-BASED SEMIMAGNETIC SEMICONDUCTORS
We present energy spectrum calculations of 5E term of Fe++ ion taking into account crystal field, spin-orbit interaction, uniaxial stress, magnetic field and dynamic Jahn-Teller effect. Basing on the obtained energy spectra we calculate magnetic properties (specific heat and magnetization) of Fe-based Semimagnetic Semiconductors. We found that presence of the JahnTeller effect has very small in...
متن کاملThree-dimensional topological insulators in I-III-VI2 and II-IV-V2 chalcopyrite semiconductors.
Using first-principles calculations within density functional theory, we investigate the band topology of ternary chalcopyrites of composition I-III-VI2 and II-IV-V2. By exploiting adiabatic continuity of their band structures to the binary 3D-HgTe, combined with direct evaluation of the Z2 topological invariant, we show that a large number of chalcopyrites can realize the topological insulatin...
