The advent of graphene, and more recently of layered 2D materials, has opened new perspectives in electronics, optoelectronics, energy harvesting and sensing applications. Layered 2D materials can be fabricated with relatively inexpensive production methods, integrated into existing semiconductor technologies, and offer new physical, chemical and mechanical properties. Electrically they can behave as metals, semiconductors, insulators or even superconductors. Consisting of covalently bonded and dangling-bond free lattices, they can form heterojunctions with each other or with bulk materials, without the need of a close lattice matching. In these heterojunctions, the participant materials are held together by weak van der Waals forces, which do not introduce significant changes at the atomic scale and essentially maintain the original electronic structure of the materials. Hence, van der Waals heterojunctions offer the opportunity to combine layers with different properties as the building blocks to engineer new functional materials for high-performance device or sensor applications. A great advantage is that the easy stacking of a variety of 2D materials allows a far greater number of combinations than any traditional growth method.
A great deal of work has been done thus far on the synthesis and characterization of layered 2D materials, such as graphene, transition metal dichalcogenides, hexagonal boron nitride, black phosphorus, silicene, organic perovskites, etc. Many of them have been used to fabricate stacked 2D-2D heterostructures, 2D/3D heterojunctions with common bulk semiconductors, such as Si, GaA, SiC or even 0D-2D and 1D-2D hybrids. The underlying physics and the possible applications in photodetection, biochemical sensing, strain gauges, photovoltaic energy generation or energy harvesting has been attracting the attention of both theorists and experimentalists.
The purpose of the present Special Issue is to collect state-of-the-art work on layered 2D materials and, in particular, on their van der Waals heterojunctions, both from a fundamental and application perspective. Review articles or research papers dealing with the fabrication and the properties of 2D materials and of their van der Waals heterojunctions, or with their use in electronic devices and sensors, are solicited and welcomed.
