Effects of phosphorus dopingviaMn₃P₂on diamond growth along the (100) surfaces

Abstract

In this study, n-type diamond crystals were synthesized via the temperature gradient method at 5.6 GPa and 1230–1245 °C by adding a Mn3P2 dopant and FeNi catalyst.

The lateral outward growth of single-crystal diamonds by two different structures of microwave plasma reactor

“…Single-crystal diamond (SCD) has broad application prospects as a superhard material. [1][2][3][4][5][6] Other physical and chemical properties of SCD are also excellent, such as its high thermal conductivity, high breakdown field, high optical transmittance, and low birefringence, and the unique spin coherence properties of the N-V center. [2][3][4] Based on the relevant characteristics, SCD can be applied in numerous areas of cutting-edge technology, such as in semiconductor power devices, high-energy particle detection, optical windows, Raman laser devices, and quantum computing.…”

“…[2][3][4] Based on the relevant characteristics, SCD can be applied in numerous areas of cutting-edge technology, such as in semiconductor power devices, high-energy particle detection, optical windows, Raman laser devices, and quantum computing. [1][2][3][4][5][6][7] At present, crystal size can restrict further applications in the field of frontier technology. Therefore, it is necessary to prepare large-size and high-quality SCD samples.…”

“…High pressure and high temperature (HPHT) and chemical vapor deposition (CVD) methods for preparing SCD are becoming more and more developed. 1,[5][6][7] Among these approaches, microwave plasma chemical vapor deposition (MPCVD) is an effective method for preparing large-size diamonds with a low dislocation density. 6,7 For the homoepitaxial lateral outward growth of SCD, the key is to effectively reduce the appearance of a polycrystalline diamond (PCD) rim and defects at the seed edges.…”

Growth characteristics of type IIa large single crystal diamond with Ti/Cu as nitrogen getter in FeNi–C system*

“…Therefore, type IIa diamond has an irreplaceable role, for example, it can be used as an optical window material of laser transmitter and has more advantageous to synthesize new semiconductors by adding sulfur, phosphorus and boron. [10][11][12][13] Presently, a large number of researchers have devoted to study of type IIa synthetic diamond.…”
