Graphene and its derivatives for Nanoscale Semiconductor Memories-A Density Functional Theory based approach

Abstract

Memory occupies large portion of semiconductor industry. A lot of researches are going about new memory materials.In this paper we explore electronic, optical and magnetic properties of graphene and graphene nanoribbons for semiconductor memory applications.Graphene is having high mobility, good scaling properties.Also it shows Ferromagnetic and anti ferromagnetic properties.Measurable Optical properties are appeared in literature. All these properties are tunable with band gap .These factors point outs that graphene is a suitable candidate for making memories of various categories such as flash,optical storage devices,magnetic RAM etc.The bandgap of the graphene is a considerable design problem when making electronic devices.But nanoribbons can solve this issue and can provide enough band gap suitable for memory devices.Short channel effects scattering,ambipolar conduction is another point that need attention
