Abstract: Abstract: 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.
