Buckling effects in AlN monolayers: Shifting and enhancing optical characteristics from the UV to the near visible light range
Nzar Rauf Abdullah, Botan Jawdat Abdullah, Hunar Omar Rashid +1
The structural, electronic, and optical properties of flat and buckled AlN monolayers are investigated using first-principles approaches. The band gap of a flat AlN monolayer is ch…
Optical conductivity enhancement and thermal reduction of BN-codoped MgO nanosheet: Significant effects of B-N atomic interaction
Nzar Rauf Abdullah, Botan Jawdat Abdullah, Yousif Hussein Azeez +2
We investigate the electronic, the thermal, and the optical properties of BN-codoped MgO monolayers taking into account the interaction effects between the B and the N dopant atoms…
Planar buckling controlled optical conductivity of SiC monolayer from Deep-UV to visible light region: A first-principles study
Nzar Rauf Abdullah, Hunar Omar Rashid, Botan Jawdat Abdullah +2
The electrical and optical properties of flat and planar buckled siligraphene (SiC) monolayer are examined using a first principles approach. Buckling between the Si and the C atom…
Role of planar buckling on the electronic, thermal, and optical properties of Germagraphene nanosheets
Nzar Rauf Abdullah, Yousif Hussein Azeez, Botan Jawdat Abdullah +3
We report the electronic, the thermal, and the optical properties of a Germagraphene (GeC) monolayer taking into account buckling effects. The relatively wide direct band gap of a…
Study of the buckling effects on the electrical and optical properties of the group III-Nitride monolayers
Nzar Rauf Abdullah, Botan Jawdat Abdullah, Hunar Omar Rashid +2
We consider electronic and optical properties of group III-Nitride monolayers using first-principle calculations. The group III-Nitride monolayers have flat hexagonal structures wi…
Electronic and Optical properties of Metallic Nitride: A comparative study between the MN (M=Al, Ga, In, Tl) monolayers
Nzar Rauf Abdullah, Botan Jawdat Abdullah, Vidar Gudmundsson
The electronic and the optical properties of metallic nitride (MN) monolayers are studied using a DFT formalism. In most of these monolayers, the electron density of the metallic a…
