About this Research Topic
Miniaturization and energy efficiency are two strongly interconnected and competing fundamental principles driving the development of modern electronics. The synthesis of high-quality two-dimensional (2D) systems, such as van der Waals heterostructures or quantum materials, plays an important role in such a roadmap. The key test for defining their potential for nanoelectronics is the investigation and determination of their optical and electronic properties. In this respect, these novel materials often host a rich phenomenology, which requires a combination of innovative experimental approaches, sophisticated modelling and refined computational methods to be understood.
This Research Topic is aimed at hosting manuscripts in the field of condensed matter physics, which are targeted at the study of the optical and electronic properties of 2D systems. The knowledge of such properties is the basic and fundamental requirement for the development of any optoelectronic device and for the design of applications. A comprehensive collection of articles covering those aspects will be used as a reference by the entire scientific community working on low-dimensional systems. The goal is to select contributions that can have an impact on the development and design of nanoelectronics applications.
The Research Topic will include the characterization of several 2D systems of technological interest, carried out with complementary experimental and theoretical techniques. These range from electronic transport to optics and spectroscopy. A few glorious examples of systems of interest are 2D materials, such as graphene or hBN and topological insulators. In the past few years these have been widely investigated in virtue of their extremely rich physical properties, such as valley-dependent spin-orbit splitting, topology-protected low-energy states, efficient charge transfer, superconductivity and so on. This Research Topic will focus particularly on properties related to optics and transport.
We therefore envision contributors to submit their work related to optoelectronic properties of two-dimensional systems and related materials, including twisted van der Waals heterostructures and other exotic systems. Theoretical works backing up experimental results or predicting novel phenomena are expected as well.
