Preface
Carbon nanowalls, nanosheets, and nanoflakes are essentially planar layered graphenes with open boundaries. This self-contained book covers all the important areas of research on carbon nanowalls and related sheet nanostructures, including synthesis techniques for carbon nanowalls, their characterization, growth mechanism and various expected applications using carbon nanowalls. Carbon nanowalls can be described as graphite sheet nanostructures with edges that are composed of stacks of planar graphene sheets standing almost vertically on the substrate. The sheets form a self-supported network of wall structures with thicknesses ranging from a few nanometers to a few tens of nanometers, and with a high aspect ratio. The synthesis methods for carbon nanowalls are similar to those used for diamond films and carbon nanotubes. To date, carbon nanowalls and related materials have been grown using various chemical vapor deposition methods. The large surface area and sharp edges of carbon nanowalls may prove useful for a number of different applications such as electrochemical devices, field electron emitters, gas storage materials, and catalyst support. Furthermore, since carbon nanowalls essentially consist of graphene sheets, they are expected to demonstrate high mobility and considerable sustainable current density. Therefore, carbon nanowalls will be used in the field of nanoscale electronic devices. Research on how to exploit the potential of graphene and to develop next-generation electronic devices using carbon nanowalls has just beg
