What does magnesium boride mean? Magnesium diboride, also known as MgB2, is an ionic chemical with hexagonal crystal structures. It’s an intercalation compound that has layers of magnesium, boron and other elements. Researchers discovered in 2001 that the superconductor of magnesium diboride is a small compound. It can turn at 40K, which is close to its absolute temperature (ie. -233°C). This superconductor’s transition temperature, which is close to double that of others of the same kind, is approximately 2030K. This temperature can be reached using liquid neon, liquid hydrogen, or closed cycle refrigerators. These are much simpler than cooling niobium alloys (K) using liquid helium. If magnesium boride is doped in carbon or any other impurities it can keep superconductivity the same as that of niobium alloys, and even higher, when there’s a magnetic field passing through. There are many potential uses for magnesium boride, including power transmission lines and sensitive magnetic fields detectors. Multi-band research on superconductivity A common characteristic of metal materials is multi-band or multi-Fermi noodles. The material will enter the superconducting phase when it opens the Fermi layer. This means that multiple energy bands may result in multiple energy gaps. Due to strong inter-band scattering, many superconducting materials will weaken the multiband effect. However, in some superconducting materials with quasi-two-dimensional characteristics, multi-band and multi-gap effects will appear due to the orthogonality of the electron motion wave functions above different energy bands. Multiband effects have also been observed in recently-discovered iron-based superconductors. This research area is an area of great interest in superconducting materials, physics and related fields. The multi-band Superconductor Magnesium Diboride is an example. The superconductor has one band of electrons, one band of hole type and one band band. Due to the special configuration of the Fermi surface (the π band is three-dimensional and the σ band is quasi-two-dimensional), its The wave vectors of electrons in different energy bands are in an orthogonal state, so that the inter-band scattering is not very strong, which makes the superconductor’s multi-band characteristics outstanding. Hall effect, which can reveal information about the carrier count and scattering rate in cyclotron motion is an effective tool for magnetoresistance. The combination of magnetoresistance, Hall effect and other methods can be used to deduce electron scattering rates for different energy bands. TRUNNANO is also known as. Lempotee Nano Technology Co.
