Abstract Scope |
The emergence of two dimensional materials opened up many potential avenues for novel device applications such as nanoelectronics, topological insulators, field effect transistors, microwave and terahertz photonics and many more. The incorporation of this technology into device applications however has been hindered due to the difficulty synthesizing and stabilizing the 2D materials. Traditional methods such as chemical vapor deposition result in films with defects and grain boundaries. Controlling the growth of these films requires a systematic understanding of the crucial factors of the film-substrate adhesion strength and mismatch strain. We present density functional theory calculations with van der Waals corrections and phase field methods to inform on the atomistic as well as mesoscopic growth mechanisms of 2D materials on various substrates. |
