Abstract

This special issue is intended to serve as a multidisciplinary forum covering broad aspects of the science, technology, and application of synthetic and natural diamonds. This special issue contains 12 papers, which highlight recent investigations and developments in diamond research related to the diverse problems of natural diamond genesis, diamond synthesis and growth using CVD and HPHT techniques, and the use of diamond in both traditional applications, such as mechanical machining of materials, and the new recently emerged areas, such as quantum technologies. The results presented in the contributions collected in this special issue clearly demonstrate that diamond occupies a very special place in modern science and technology. After decades of research, this structurally very simple material still poses many intriguing scientific questions and technological challenges. It seems undoubted that diamond will remain the center of attraction for many researchers for many years to come.

Highlights

  • Diamonds, which possess a remarkable range of extreme and outstanding properties superior to other materials, have been attracting huge interest as a versatile and technologically useful material.Advances in diamond synthesis and growth techniques have paved the way for this unique material to many existent and prospective applications, which range from optics and electronics to biomedicine and quantum computing

  • The modern era of diamond as a technological material began in the 1950s after the first reports on the successful synthesis of diamond through the high pressure high temperature (HPHT) technique [19,20]

  • In order to use this property of the diamond Raman spectrum to full extent, it is important to understand the physical mechanisms behind the effect of defects and impurities on the vibrational properties of diamond

Summary

Introduction

Diamonds, which possess a remarkable range of extreme and outstanding properties superior to other materials, have been attracting huge interest as a versatile and technologically useful material. Diamond is an allotrope form of carbon that is thermodynamically stable at high pressures It has a face centered cubic structure with each carbon atom covalently bonded to its four nearest neighbors in a regular tetrahedron. As it frequently happens, solutions to some particular issue may lie just a step aside of the subject area and breakthroughs are only possible with a multidisciplinary approach. Earth sciences and the latter in the material science, physics, and engineering
