AbstractTwo-dimensional (2D) van der Waals (vdW) materials possess a crystal structure in which a covalently-bonded few atomic-layer motif forms a single unit with individual motifs being weakly bound to each other by vdW forces. Cr2Ge2Te6 is known as a 2D vdW ferromagnetic insulator as well as a potential phase change material for non-volatile memory applications. Here, we provide evidence for a dimensional transformation in the chemical bonding from a randomly bonded three-dimensional (3D) disordered amorphous phase to a 2D bonded vdW crystalline phase. A counterintuitive metastable “quasi-layered” state during crystallization that exhibits both “long-range order and short-range disorder” with respect to atomic alignment clearly distinguishes the system from conventional materials. This unusual behavior is thought to originate from the 2D nature of the crystalline phase. These observations provide insight into the crystallization mechanism of layered materials in general, and consequently, will be useful for the realization of 2D vdW material-based functional nanoelectronic device applications.

AbstractWithin the broad and deep field of topological materials, there are an ever-increasing number of materials that harbor topological phases. While condensed matter physics continues to probe the exotic physical properties resulting from the existence of topological phases in new materials, there exists a suite of “well-known” topological materials in which the physical properties are well-characterized, such as Bi2Se3 and Bi2Te3. In this context, it is then appropriate to ask if the unique properties of well-explored topological materials may have a role to play in applications that form the basis of a new paradigm in information processing devices and architectures. To accomplish such a transition from physical novelty to application based material, the potential of topological materials must be disseminated beyond the reach of condensed matter to engender interest in diverse areas such as: electrical engineering, materials science, and applied physics. Accordingly, in this review, we assess the state of current electronic device applications and contemplate the future prospects of topological materials from an applied perspective. More specifically, we will review the application of topological materials to the general areas of electronic and magnetic device technologies with the goal of elucidating the potential utility of well-characterized topological materials in future information processing applications.

A method for modeling and printed circuit board layout in the form of a 3D model in one of the digital solutions designed for this task, Altium Designer, is proposed. The practical significance of the work is the study of the basic software libraries in terms of their creation, filling and application when working with the project, as well as of the algorithm for constructing an electrical circuit in the Altium Designer program, layout and design of the simplest circuit on the board. In the course of the work, the algorithm and rules for creating a library of three-dimensional models of components, a library containing conditional graphic designations of the corresponding components, a schematic diagram of the device, a three-dimensional model of the board and the construction of conducting tracks on it are described. The components and circuits used in the work are publicly available on the Internet, which allows anyone to work over the entire algorithm for studying and honing the skills of designing printed circuit boards, both by students studying at a higher educational institution and by fully-fledged specialists. This work can be used not only for teaching students in the field of electronic device development in terms of their design and for organizing laboratory work, but also for creating and designing real devices both in production and within a higher educational institution, for example, for creating a laboratory bench. The introduction and study of this software is carried out at the Department of Radio-Electronic Systems and Complexes of one of the leading engineering universities of the Russian Federation — the Bauman Moscow State Technical University.
