Growth of nanocrystalline MgSe thin films by spray pyrolysis

The nanocrystalline MgSe thin films were deposited onto glass substrates by spray pyrolysis method at 523 K temperature using MgCl2 and SeO2 precursors. Structural, morphological, optical and electrical properties of MgSe thin films have been studied. The structural studies revealed that the as-depo...

Description
Summary:The nanocrystalline MgSe thin films were deposited onto glass substrates by spray pyrolysis method at 523 K temperature using MgCl2 and SeO2 precursors. Structural, morphological, optical and electrical properties of MgSe thin films have been studied. The structural studies revealed that the as-deposited MgSe thin films are nanocrystalline in nature with cubic lattice. The morphological investigations show that the total substrate surface is well covered by the spherical star type grains with MgSe nano-rods at some places. The optical absorption measurements confirm that the MgSe films have direct optical band gap of the order of 2.45 eV. The electrical characterizations indicate that as deposited P-type MgSe films are semiconducting in nature. •MgSe nano-rods were deposited by spray method.•The films are nanocrystalline with cubic lattice.•Electrical characterization confirms semiconducting nature.
