Abstract
The adsorption of organic molecules onto surfaces is a topic of increased interest in some scientific and technological fields, since the molecular interactions at the molecule/surface interface play an important role in several applications. For example, with the adsorption of organic molecules, material surfaces can be provided with unique characteristics of the organic molecules, such as their absorption spectrum, chemical affinity and hydrophobicity/hydrophilicity. This process is known as organic functionalization, whose ultimate goal is the production of novel nano-electronic devices with properties such as light emission, light detection and chemical sensitivity. In this work, we study the adsorption of unsaturated hydrocarbons, onto material surfaces of two dimensional systems, such as graphene, silicene and germanene. Recent achievements associated with graphene have led to the research of analogue two-dimensional structures, such as silicene and germanene. In general, these systems are promising substrates for organic functionalization.
