چکیده
Optoelectronic and thermoelectric properties of A3InAs3 (A = Sr Eu) Zintl compounds are investigated using FP-LAPW method with LDA, GGA mBJ potentials for Sr3InAs3 in addition Hubbard (U) Eu3InAs3 based on DFT. Electronic reveal that both the direct bandgap semiconductors their semiconducting nature is also supported by electrical resistivity (conductivity). The value ranging from 0.50 to 0.74 decreasing replacement Eu. results divulge optically active infrared region anisotropic can be used as a shield ultraviolet radiation potential candidate optoelectronic devices. Negative -383 -411 µV/K Seebeck coefficients suggest electrons majority charge carriers. Low thermal conductivity, high coefficient power factor indicating matrix application.

متن کاملInter-band Tunnel Transistor Architecture using Narrow Gap Semiconductors
The inter-band tunnel transistor (TFET) architecture features a subkT/q sub-threshold slope operation and can potentially support high ION/IOFF ratios over small gate voltages. Based on twodimensional numerical simulations, we investigate TFET in various material systems ranging from silicon to indium arsenide. TFET performance can be enhanced when heterojunctions are employed at the source sid...
متن کاملZintl phases for thermoelectric devices.
By converting waste heat into electricity and improving the efficiency of refrigeration systems, thermoelectric devices could play a significant role in solving today's energy problems. Increasing the thermoelectric efficiency (as measured by the thermoelectric material's figure-of-merit, zT) is critical to the development of this technology. Complex Zintl phases, in particular, make ideal cand...
