Book excerpt: Calculations and Simulations of Low-Dimensional Materials A comprehensive guide to methods for calculating and simulating the properties of low-dimensional materials Two-dimensional materials are those, such as graphene and 2D oxides, whose thickness is so small as to approach the atomic scale. Potential applications for these materials exist in an enormous range of scientific and industrial fields.

This book was released on 2018 with total page 158 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this thesis, we develop new theories and perform simulations to study low dimensional materials such as directed polymers (1+1 dimension) and silicene nanoclusters (0 dimension) that can be used for nanotechnology applications. In recent years, there has been a flurry of experimental and theoretical activities aimed at exploring topological insulators in classical contexts. The aim is to develop novel types of robustness within optical and mechanical materials. Virtually all of these proposals and experiments rely on wave propagation described by Newton's or Maxwell's equations and for the most part ignore interactions between particles or waves. In the first three chapters of this thesis, we explore whether it is possible to adopt similar strategies at the scale of soft materials where transport is typically governed by diffusion processes rather than wave propagation (sound waves are typically suppressed by dissipation). Moreover, in soft materials, thermal fluctuations and interactions are strong and cannot be neglected. We present a general strategy to create topologically protected gapped states in soft matter systems described by the diffusion equation with the presence of strong many-body interactions. We apply our framework to a system of many interacting polymers on a spatially modulated substrate. In this case, the topologically protected state is not a wave robustly moving along the edge of the finite systems, but rather a tilt in the collective orientation of the polymer liquid. The resulting tilt angle is proportional to a topological index called Chern number, and thereby exhibits robustness against substrate disorder. We corroborate these conclusions with numerical simulations. The miniaturization of electronics will depend on our capability to engineer nanoscaled hetero-structures. Therefore, our study on the rest of this thesis focuses on the electronic and magnetic properties of finite rectangular silicene fragments to which we refer as silicene nanoclusters. We use first-principles calculations to demonstrate that the multiplicity of the the ground (neutral) state of a silicene nanocluster (SiNC) is determined by the nature of its nanoribbon edges (i.e. armchair na or zigzag nz,). For instance, a rectangular SiNC with edges na > nz, has a nonzero net spin, resembling an artificial ferromagnetic state. In addition, we calculate the Raman spectra which allowed us to detect a D peak, which is given by the armchair edges with a triplet ground state. In general, this principle of varying the length of the SiNCs can be used to introduce large net spin as well as interesting spin distributions in silicene. The observation of a triplet ground state in the armchair edges can be used for the design of spintronic devices. High-performance materials rely on small reorganization energies to facilitate both charge separation and charge transport. Here, we found that rectangular SiNCs could have small reorganization energies depending on the multiplicity of the ground state of the SiNC. These rectangular SiNCs feature large electron affinities and highly stabilized anionic states indicating that these finite structures are prone to behave as n-type semiconductors that could be used in low dimensional hetero-junctions. Moreover, we discovered a possible connection between the energy response of the material with the distortion of its buckled lattice which would be advantageous to consider while designing such electronic devices.

This book was released on 2012-12-06 with total page 329 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains papers presented at the NATO Advanced Research Workshop (ARW) Dynamic Interactions in Quantum Dot Systems held at Hotel Atrium in Puszczykowo, near Poznan, Poland, May 16-19,2002. The term low-dimensional systems, which is used in the title of this volume, refers to those systems which contain at least one dimension that is intermediate between those characteristic ofatoms/molecules and those ofthe bulk material. Depending on how many dimensions lay within this range, we generally speak of quantum wells, quantum wires, and quantum dots. As such an intermediate state, some properties of low-dimensional systems are very different to those of their molecular and bulk counterparts. These properties generally include optical, electronic, and magnetic properties, and all these are partially covered in this book. The main goal of the workshop was to discuss the actual state of the art in the broad area ofnanotechnology. The initial focus was on the innovative synthesis of nanomaterials and their properties such as: quantum size effects, superparamagnetism, or field emission. These topics lead us into the various field based interactions including plasmon- magnetic spin- and exciton coupling. The newer, more sophisticated methods for characterization of nanomaterials were discussed, as well as the methods for possible industrial applications. In general, chemists and physicists, as well as experts on both theory and experiments on nanosized regime structures were brought together, to discuss the general phenomena underlying their fields ofinterest from different points ofview.

Book excerpt: The fascinating two-dimensional (2D) materials are being unconsciously applied in various fields from science to engineering, which is benefited from the glamorous physical and chemical properties of mechanics, optics, electronics, and magnetism. The representative 2D thermoelectric/piezoelectric materials can directly convert thermal/mechanical energy into electrical energy, which can resolve the energy issues and avoid further environmental deterioration. The thermoelectric or piezoelectric properties of various 2D materials, such as graphene, hexagonal boron nitride, black phosphorus, transition metal dichalcogenides (TMDs), arsenene, metal carbides and nitrides (MXenes), and so on, have been investigated in detail. Although tremendous progress has been achieved in the past few years, these properties still need to be improved for their practical application by designing new 2D materials, strain engineering, chemical functionalization, etc. In addition to this, in 2D materials, there are many other novel physical properties, such as magnetism, topology, valley, and so on. The combination of thermoelectricity/piezoelectricity with other unique properties may lead to novel device applications or scientific breakthroughs in new physics. Overall, the emergence of 2D thermoelectric and piezoelectric materials has expanded energy conversion research dramatically. By combing this new device concept with the novel 2D materials, original devices should have potential applications in energy harvesting.
