| Resumo | |
We propose a new 2D semiconductor material (TTA-2D) based on the molecular structure of ThiopheneTetrathia-Annulene (TTA). The TTA-2D structural, electronic, and optical properties were investigated ab initio methods. Our results show that TTA-2D is a small indirect bandgap semiconductor (0.6 semiconductor-metal transition can be induced by applying a uniaxial strain. Our results also show that is thermally stable up to T = 1000 K. TTA-2D absorbs in a large spectral range, from infrared to ultraviolet regions. Values of refractive index and reflectivity show that TTA-2D reflects only 10% of the incident light visible region. These results suggest that TTA-2D is a promising material for solar cell applications. (AU) | |
