Description
Needle-shape IrSe2 microrods, with maximum thickness of 6 μm, maximum width of 17 μm, and 20 mm in length were synthesized by the chemical vapour transport method with ICl3 as the transporting agent. Energy-dispersive X-ray spectroscopy showed an atomic Ir to Se ratio of 1:(2 - δ), where 0 < δ < 0.09. Scanning electron microscopy showed single crystalline structure for the synthesized IrSe2. The electrical properties of the IrSe2 were studied via temperature dependent transport properties measurements in the range of 20-510 K. The thermal band gap was evaluated to be 0.17 eV. Room temperature Hall effect measurement showed p-type semiconducting character for the sample.
