The discovery of monolayer graphene led to a Nobel Prize in Physics being awarded in 2010. This has stimulated further research on a wide variety of two-dimensional (2D) layered materials. The coupling of metallic graphene, semiconducting 2D transition metal dichalcogenides (TMDCs) and black phosphorus have attracted a tremendous amount of interest in new electronic and optoelectronic applications. Together with other 2D materials, such as the wide band gap boron nitride nanosheets (BNNSs), all these 2D materials have led towards an emerging field of van der Waal 2D heterostructures. The papers in this book were originally published by Electronics (MDPI) in a Special Issue on “Two-Dimensional Electronics and Optoelectronics”. The book consists of eight papers, including two review articles, covering various pertinent and fascinating issues concerning 2D materials and devices. Further, the potential and the challenges of 2D materials are discussed, which provide up to date guidance for future research and development.

This thesis describes the fabrication of metal-insulator-semiconductor (MIS) structures using very high permittivity dielectrics (based on rare earths) grown by high-pressure sputtering from metallic targets. It demonstrates the possibility of depositing high permittivity materials (GdScO3) by means of high pressure sputtering from metallic targets using in situ plasma oxidation on Si and indium phosphate (InP) substrates. The advantage of this system is the high working pressure, which causes the particles to undergo multiple collisions and become thermalized before reaching the substrate in a pure diffusion process, thus protecting the semiconductor surface from damage. This work presents a unique fabrication using metallic targets and involving a two-step deposition process: a thin metallic film is sputtered in an Ar atmosphere and this film is then plasma oxidized in situ. It also demonstrates the fabrication of GdScO3 on Si with a permittivity value above 30 from metallic Gd and Sc targets. Since co-sputtering was not possible, a nanolaminate of these materials was deposited and annealed. The electrical properties of these devices show that the material is highly interesting from a microelectronic integration standpoint.
