Role of planar buckling on the electronic, thermal, and optical properties of Germagraphene nanosheets

We report the electronic, thermal, and optical properties of a Germagraphene (GeC) monolayer taking into account buckling effects. The relatively wide direct band gap flat GeC nanosheet can be changed by tuning planar buckling. A has an sp 2 hybridization in which contribution s -orbital is half p leading to stronger σ - bonds compared π bonds. Increasing buckling, decreased while increased resulting 3 -hybridization bond becomes than bond. As result, buckled reduced thus thermal are significantly modified. find that heat capacity at low values caused anticrossing acoustic phonon modes affecting scattering processes. properties, such as dielectric function, refractive index, electron energy loss spectra, absorption, conductivity show activities visible light region GeC. red shifted from near ultraviolet region, when increased. confirm seen another parameter improve monolayers for optoelectronic devices.
