Abstract:

Beyond graphene, which is intensively studied over more than one decade, the other related materials remain almost unexplored. The research activities in the field of other layered materials like phosphorene, arsenene, silicene and germanene are rapidly growing in the last few years. Compare to graphene, all these materials are non-zero band-gap semiconductors. This property opens new application possibilities in electronic and optoelectronic devices. The properties of 2D materials can be further controlled by their functionalization. The chemistry of materials beyond graphene is none explored and shows high application potential in many fields. Compared to the graphene and pnictogen group, the chemical exfoliation method must be applied for synthesis of silicene / germanene derivatives using Zintl phase compounds like CaGe2 and CaSi2. Various methods well known from organic chemistry can be applied for synthesis of tetrel derivatives reaching almost complete derivatization of 2D material skeleton. 

Zdenek Sofer is a professor at the University of Chemistry and Technology Prague since 2019. He received his PhD also at University of Chemistry and Technology Prague, Czech Republic, in 2008. During his PhD he spent one year in Forschungszentrum Julich (Peter Grünberg Institute, Germany) and also one postdoctoral stay at University Duisburg-Essen, Germany. Research interests of prof. Sofer concerning on 2D based materials covering graphene, pnictogens, silicene, layered chalcogenides and other 2D nanomaterials, its chemical modifications and various applications covering electrocatalysis, gas separation and energy storage. Currently prof. Z. Sofer acts as an associated editor of FlatChem Journal. He has published over 500 articles, which received over 18 200 citations (h-index of 66).​
