| Abstract: | A new compound KHg4InSe6 was synthesized at 550℃ by means of a solid reactive flux method.The compound was found to be lamellar by SEM. EPM-810Q electron probe microanalyser was used for the qualitative and quantitive elemental analysis of the single crystal. The crystal was indentified to be new by EDS showing a molar ratio NK∶NHg∶NIn∶NSe≈1∶4∶1∶6. The new crystal was further indentified by powder X-ray differaction experiment. The thermal stablility and light absorbablity of the compound were also investigated by using differential thermal anlysis and diffuse reflective spectra techniques. The experimental results show that the compound can be thermally stable below 300℃ and it is a kind of semiconductor with an energy gap of 0.5eV. |
