Special Issue Information

Dear Colleagues, 

Since Geim and Novoselov discovered graphene, a new generation of materials has entered the world of nanoscience, generally known as two-dimensional materials. They are characterized by unique physical properties with respect to the bulk in nature: diverse electrical behavior, from metals and semiconductors to insulators; peculiar nanomechanics and tribology; and, finally, extreme thermal conductivities. In the past few years, structures made of a single sheet or a few layers of two-dimensional materials have been intensively investigated. Many physical properties have been successfully explored, although further investigations are paramount to advance in this new area. Subsequently, scientists have started to build systems resulting from the combination of two or more two-dimensional materials. Typically, such heterostructures consist of vertical stacks obtained via the successive superposition of single layers, often varying the orientation of adjacent layers or even integrating other molecules, with the intent of tuning their physical and chemical properties. However, the realization of these stacks is not trivial, and to investigate new phenomena and create new devices, it is equally important to realize such systems and characterize them at the nanoscale. In this issue, we will publish the latest achievements in terms of the design, characterization, and application of two-dimensional materials heterostructures.

Under the deformation potential model, the superconducting phenomenon in ABC-stacked multilayer graphene under a vertical electric field is investigated using linear combination operators and unitary transformation methods. Through the deformation potential model applied to a linear continuous medium, the effect of the external electric field is converted into the deformation potential energy of the crystal. Deformation potential phonons (LA phonons) act as propagators, generating electron–electron interactions. As the electric field increases, the ratio of the electric displacement vector to the dielectric function (D/ε) rises, leading to an increase in the electron ground-state energy, the opening of the band gap, and an enhancement of the attractive electron–electron interaction. With further increases in the external electric field, the deformation potential constant of the crystal (Dl) increases. When the phonon vibration frequency (ω) is around 8.5 THz, and the conditions are satisfied—where the wave vectors of different LA phonons are equal in magnitude and opposite in direction, and the electron spins are opposite—the attractive electron–electron interaction reaches its maximum (Hceff), resulting in the emergence of superconductivity. Our study also provides a new perspective for understanding the unique quantum properties—such as strong correlations, superconductivity, and ferromagnetism—in different stacking configurations like AB, ABC, and ABCA.
