| Abstract: | Undoped InSe and Ho doped InSe single crystals were grown by Bridgman-Stockberger method. The InSe crystals both undoped and doped with different ratios of (InSe:Ho0.0025, InSe:Ho0.025, InSe:Ho0.005 and InSe:Ho0.05) had no cracks or voids on the surface. No polishing or cleaning treatments were carried out on the cleaved faces of these samples because of the natural mirror-like cleavage faces. The absorption measurements were carried out in the temperature range 10-320 K and the external electric field effect on the absorption measurements was investigated. The absorption edge shifted towards the longer wavelengths under an electric field as 6 kV/cm. Using the electric field shits, effective mass values are calculated for all the samples. |
