Two dimensional (2D) layered materials have attracted intense research interest in both fundamental study and practical applications because of their intriguing optical and electronic properties. Thanks to the weak interlayer van der Waals force, these 2D materials can be further stacked to form artificial heterostructures without constraints from lattice mismatch. There, new degree of freedoms including components, structures and twisting angles provide unprecedented control of properties and functionalities. For example, heterostructures consisting of 2D semiconductors with strong light-matter interaction and excitonic effect have opened new door to ultrathin optoelectronics. Moreover, when two monolayers are super-imposed with carefully tuned twisting angles, a 2D moiré superlattice is formed, which has led to recent breakthrough in superconducting and correlated physics.
The scope of this special topic in Frontiers of Physics would cover all the aspects of experimental and theoretical studies on the optical properties and photophysical processes in 2D materials, heterostructures and Moiré Superlattices, including but not limited to:
● 2D exciton optical properties and dynamics;
● Interfacial exciton charge/energy transfer;
● Intralayer/interlayer exciton recombination and transport;
● Spin and valley relaxation and manipulation;
● Nonlinear optics and modulation;
● Moiré modulated optical properties and exciton dynamics;
● Correlated electronic states and hybrid exciton.

As Moore's Law approaches the physical limit, the traditional von Neumann architecture is facing challenges, among them, one of the most promising device candidates is memristor. In recent decades, memristors have developed rapidly due to their simple sandwich structure, good compatibility and availability with existing CMOS processes. Recently reported memristors show attractive features, such as high ON/OFF ratio, low power consumption, fast switching speed and high durability, which can respond to the needs of emerging applications. These characteristics of the memristor are produced by applying an external bias voltage to change the resistance state. By exploiting complex material types and a variety of resistive mechanisms, the research on memristors and their potential applications has become the frontier and hotspot in physics, electronics, materials, nano and other fields, and has shown the characteristics of interdisciplinary integration. In the field of basic research and practical application of memristors, their complex material types and various resistance mechanisms play a crucial role in device performance and application prospects. The material types and resistance variation mechanism of memristors have laid a solid foundation for predicting and improving device performance and expanding application prospects. Whether it is a non-volatile memristor or a volatile memristor, the material type and resistance variation mechanism are extremely important in influencing the application prospects of information storage, neural networks and logic operations. In particular, to address power and energy efficiency problems in neuromorphic computing, memristors are strong candidates. These endow memristors with the potential to trigger a circuit revolution, which may once again extend the life of Moore's Law, open up new directions for research in the field of information storage and information processing, and its industrialized application may also bring about a new round of technological revolution.
The scope of this focus issue in Frontiers of Physics would cover the aspects on the materials, mechanisms and applications of memristors from experimental synthesis, characterizations, theoretical calculations, etc. Articles reporting on the latest progress in the controllable growth of new materials, switching mechanism, application prospect of memristors and the exploitation of them towards innovative and practical devices are expected. Research works addressing approaches to switching mechanism and application prospect of memristors from both experimental and theoretical points of view are also welcome.

In recent decades two-dimensional (2D) layered materials have attracted intense interest because of their unique mechanical, electronic and optical attributes that emerge from the exotic quantum collective behaviors of electrons confined within the atomically thin layers. By exploiting the 2D structural feature and unique material properties, 2D materials and their heterostructures have been explored as promising candidates for the applications in electronics, optoelectronics, sensing, catalysis, biomedicine, etc. In the fields of both fundamental research and practical applications in the 2D materials, surface and interface play crucial roles in modulating material properties and improving devices performance. Significant efforts have been directed towards the surface and interface engineering that is extremely important no matter the 2D materials are fabricated through the bottom-up or top-down processes. These endow emerging new properties of the 2D materials and enhanced performance of bespoken devices.
