Optical Band Gap Energy Estimation Of Undoped And Go Doped Zno Thin Zno, which has high electrochemical stability, wide band gap energy, large excitonic binding energy, intense near band excitonic emission and is non toxic, have potential applications in all fields. this chapter reviews the structural, optical and electrical properties of undoped and doped zno thin films. the type of doping highly influences the structural properties such as grain size. Download scientific diagram | optical band gap energy estimation of undoped and go doped zno thin films from publication: physical properties of graphene oxide go doped zno thin films for.
Optical Band Gap Energy Estimation Of Undoped And Go Doped Zno Thin The variation of the correlate urbach energy is shown in fig. 1, significant correlations were found between the urbach energy and the band gap energy values of the zno thin films as a function of optical gap energy. however, can be used others formulas as expressed as: (2) e u = a e g b c × m d m. table 2. The band gap energy of pure zno was 3.1 ev. the doped samples exhibited better optical properties in comparison with pure zno. a slight decrease in the band gap energies of ni zno was observed in. The proposed model reproduces the values of the optical band gap energy of the investigated thin films that are in good agreement with tauc plot method and other optical models. we found that optical band gap of b zno has decreased from 3.434 ev to 3.256 ev as boron concentration in zno films is increased from 0% to 10%. The optical band gaps of the nominally undoped and zno: ga films were estimated via the tauc plot (fig. 4b) to be 3.25, 3.31, 3.55 and 3.52 ev for the 0,1, 5, 8 at.% ga doped films, respectively.

The band gap energy of zno:co thin films increased after doping from 3.25 to 3.36 ev; however, the optical gap of zno:in decreases after doping from 3.25 to 3.18 ev, indicating the increase and. It is presented the example to estimate the optical band gap of undoped and fe doped zno thin films by the intersection of the linear region on the \(h\nu\) axis gives the e g. fig. 3. the variation of ( ahν ) 2 as a function of hν for all deposited films for calculate optical energy.
