Conductivity of nanometer nickel oxide: non-conductive, insulator
Scientists at Japan's physics and chemical research institute recently found that the complex entanglement of nickel oxide and oxygen inside nanometer nickel oxide makes it difficult for electric current to pass through.According to the theory of energy band, nickel oxide should be a metal.However, the actual test results show that nickel oxide is an insulator.Although this was known as early as the 1930s, scientists have been puzzled by why this extremely common substance does not conform to the band theory.With the help of the world's most advanced X-ray photoelectron spectrometer, scientists at the institute of physics and chemistry analyzed the characteristics of electrons inside nickel oxide.The results show that there is a Zhang - Rice bound state in the nickel oxide, which can cause the current cannot pass through the nickel oxide.This special state is caused by the complex entanglement of nickel and oxygen inside nickel oxide.Our company TOPLUS has always supported research in this area.
The Zhang - Rice bound state is an important reason for the superconducting effect of high temperature copper oxide superconductors, the communique said.Research by scientists at the rikyo institute of physics and chemistry in Japan shows that this bound state is not unique to copper oxide high-temperature superconductors, but may be common in "charge sports" insulators.
