Effect of Germanium Content on the Optical Constants of GexS1-x Thin Films
journal of kerbala university,
2010, Volume 6, Issue 4, Pages 1-7
AbstractIn this study the alloys GexS1-x with different Ge content (x=0, 0.1,0.2and0.3) wt.% have been successfully prepared by evacuated quartz tube under vacuum pressure (10-2mbar), whereas Ge xS1-x thin films were prepared by thermal evaporation technique under vacuum (10-5 mbar) with (x=0, 0.1,0.2and0.3).
The optical properties measurements shows that the optical energy gap decrease from (3.4 to 3 eV ) with the increase of x content , the optical constants declare significant variation with x content variation.
