Eight applications of spherical nanodiamond particles in biomedical fields

Nanodiamond is diamond with a particle size of less than 100nm, which is a new and important member of the carbon nanometer family.

A Review of Research on Diamond, the Ultimate Semiconductor Material

The excellent physicochemical properties of diamond make it widely used in many fields. Diamond is an indirect bandgap semiconductor material with a forbidden bandwidth of about 5.2eV, thermal conductivity as high as 22W/(cmK), and room temperature electron and hole mobility as high as 4500cm2/(V.s) and 3380cm2/(V.s), which is much higher than that of the third-generation semiconductor materials, GaN and SiC, so diamond has wide application prospects for the high-temperature operation of high-power power power electronics devices, high-frequency high-power microwave devices, and also has a great exciton binding energy (80meV), which makes it widely used in many fields. Therefore, diamond has a wide range of application prospects in high power power power electronic devices, high frequency and high power microwave devices. In addition, because diamond has a large exciton binding energy (80meV), so that it can realize high-intensity free exciton emission (light wavelength of about 235nm) at room temperature, which has a greater potential in the preparation of high power deep ultraviolet light-emitting diodes, and also plays an important role in the development of the extreme ultraviolet, deep ultraviolet, and high-energy particle detectors. Although there are still many difficulties in the growth of semiconductor diamond materials and the development of devices, it can be predicted that the application of semiconductor diamond materials and devices is very likely to bring about significant changes in science and technology in the near future.

What is Functional Diamond? How is it synthesized and what are its development prospects?

Diamond has excellent electrical properties: ultra-wide band gap, ultra-high breakdown field strength, high electron and hole mobility, which is expected to become the "ultimate semiconductor"; in acoustics, diamond has the highest surface acoustic wave velocity and extremely high Young's modulus among all materials; in optics, diamond can pass through photons with energies less than the band gap, ranging from the far infrared to the ultraviolet; in thermology, its thermal conductivity exceeds that of copper, and therefore has the potential for cross-field applications. energy photons; thermally, its thermal conductivity exceeds that of copper, so diamond has the potential for cross-cutting applications. Table 1 shows the properties of diamond materials and their corresponding application areas.

Diamond, a wonder in the field of functional materials

As a diamond application, it involves a wide range of technologies and is very difficult, requiring mutual cooperation and research in various fields before it can be realized in a relatively short period of time. In the future, there is a continuous need to develop and improve the CVD diamond growth technology, to develop the CVD diamond film in acoustic, optical, electrical applications, it has become a high-tech development of the twenty-first century new materials. the application of CVD can be used for both engineering materials, but also can be used as a functional material, the following is only a little bit of its functional applications to introduce.
