Structure and optical properties of pbi2 thin film by thermal evaporation technique

Abstract EN

In this search structural, optical and electrical properties were studied by preparing a sample of lead iodide applied to glass bases by thermal evaporation process.

the film showed a hexagonal crystalline shape.

the value of the energy gap for a sample of200 nm thickness is 2.9051 ev the intensity is at the plane (003) it’s equal 12.5 nm in this research the value of the energy gap was (2.15ev-2.33) ev and the electrical properties were studied for a sample of.

the measurements were made for the electrical conductivity, mobility, carrier’s concentration and finally the hall coefficient.

the results are (1.038*10-5, 0.6727*10+2, 1.009*1012 and 2.631*106) respectively
