Boron nitride was first produced in the 18th century and, by virtue of its extraordinary mechanical strength, has found extensive application in industrial processes since the 1940s. However, the more recent discovery that boron nitride allotropes are as structurally diverse as those of carbon (e.g. fullerenes, graphene, carbon nanotubes) has placed this material, and particularly its low-dimensional allotropes, back at the forefront of modern material science. This book provides a comprehensive history of this rapid rise in the status of boron nitride and boron nitride nanomaterials, spanning the earliest examples of three-dimensional boron nitride allotropes, through to contemporary structures such as monolayer hexagonal boron nitride, boron nitride nanomeshes, boron nitride nanotubes and the incorporation of boron nitride into cutting-edge van der Waals heterostructures. It specifically focuses on the properties, applications and synthesis techniques for each of these allotropes and examines how the evolution in boron nitride production methods is linked to that in our understanding of how low-dimensional nanomaterials self-assemble, or ‘grow’, during synthesis. The book demonstrates the key synergy between growth mechanisms and the development of new, advanced nanostructured materials.

A hexagonal boron nitride nanosheet (BNNS) is an atomic-thick 2D material that exhibits many interesting properties such as high chemical stability and excellent mechanical and thermal properties. In Chapter One, the authors introduce two methods for the exfoliation of BNNS from hexagonal boron nitride (hBN). Then, methodologies for the surface functionalisation and nanocomposite construction are demonstrated by two BNNS based nanocomposites. The catalytic performance of the BNNS based nanocomposites is also evaluated and discussed in detail. Chapter two evaluates the formation of rolled hexagonal boron nitride nano-sheets (h-BN nanoscrolls) on their unique morphology, magnetic properties and applications. Due to the high chemical and thermal stabilities, as well as atomically smooth surfaces with free of dangling bonds, hBN has been used as barriers, passivation and support layers in 2D electronic devices, to maximise the electrical and optical characterisation of 2D materials. However, there still remains a challenge in obtaining large-area and high-quality hBN film for real 2D electronic devices. Chapter Three focuses on chemical vapor deposition (CVD), a promising method to overcome these limitations. Chapter Four discusses how a boron doped armchair graphene ribbon has been shown by cyclic voltammetry to be a potential catalyst to replace platinum, however the reaction catalysed was not identified. The authors use density functional calculations to show the reaction catalysed is likely dissociation of HO2. Chapter Five reveals a novel and industrially feasible route to incorporate boron nitride nanoparticles (BNNPs) in radiation-shielding aerospace structural materials. Chapter Six deals with the preparation and characterisation of boron nitride nanotube (BNNT)-reinforced biopolyester matrices. The morphology, hydrophilicity, biodegradability, cytotoxicity, thermal, mechanical, tribological and antibacterial properties of the resulting nanocomposites are discussed in detail. Chapter Seven presents theoretical estimations regarding the compressive buckling response of single walled boron nitride nanotubes (SWBNNTs), which have a similar crystal structure as single walled carbon nanotubes (SWCNTs). Moreover, SWBNNTs have excellent mechanical, insulating and dielectric properties. Finally, Chapter Eight shows how the different exchange mechanisms can be distinguished and measured by studying solid films where part of the 3He is replaced by immobile Ne atoms. The authors also show how the formation energy of vacancies and vacancy tunneling frequency can be obtained from NMR studies at high temperature.

This thesis focuses on the growth of a new type of two-dimensional (2D) material known as hexagonal boron nitride (h-BN) using chemical vapor deposition (CVD). It also presents several significant breakthroughs in the authors’ understanding of the growth mechanism and development of new growth techniques, which are now well known in the field. Of particular importance is the pioneering work showing experimental proof that 2D crystals of h-BN can indeed be hexagonal in shape. This came as a major surprise to many working in the 2D field, as it had been generally assumed that hexagonal-shaped h-BN was impossible due to energy dynamics. Beyond growth, the thesis also reports on synthesis techniques that are geared toward commercial applications. Large-area aligned growth and up to an eightfold reduction in the cost of h-BN production are demonstrated. At present, all other 2D materials generally use h-BN as their dielectric layer and for encapsulation. As such, this thesis lays the cornerstone for using CVD 2D h-BN for this purpose.

The properties, such as density and dielectric constant, of materials prepared by the CVD depend upon reaction parameters, such as pressure and temperature. The degree of anistropy of the CVD products depends primarily upon the initial reactants and secondarily upon the reaction parameters of temperature and pressure. In the report the preparation of anistropic and isotropic boron nitride (BN) is described. Two methods of preparation of the anistropic material have been investigated. One method uses ammonia and boron trichloride as the starting materials while the second method begins with beta-trichloroborazole. It will be shown that beta-trichloroborazole is a logical intermediate of the ammonia-boron trichloride system and that the two methods are, therefore, essentially equivalent. A theory is presented that not only accounts for the fact that BN formation occurs only at the hot substrate but is capable of predicting the requirements for the formation of the isotropic or anistropic forms. It should be shown that at the hot substrate a surface reaction takes place that results in the deposition of BN in an ordered anistropic form. In the reaction used for the formation of anistropic BN, water vapor is not present to disturb the initial anistropy. (Author).
