In the literature, numerous approaches to conventional soft electronics have been implemented in the form of flexible platforms, such as elastomer substrate, human skin etc. Recently, research on graphene-based optoelectronics has introduced a foldable and stretchable device due to its outstanding tensile strength and atomic structure. Along with this, its unique electronic properties – a tunable band gap induced by heterogeneous atom doping, coupled with the potential of hybrid component structures and mechanical stress, forms the basis for this study to investigate the absorption spectrum under these three conditions. This study is of significant importance to understand the relevant experiments and design optoelectronic devices. In this work, we use Density Functional Theory (DFT) and various software packages to model and simulate the spectral properties of graphene and investigate the doping and external stress effect on the optical properties of foldable and stretchable graphene.
