Mott threshold
Nettet17. feb. 2024 · Abstract. By using first-principles calculations we put forward the Cu-dicyanoanthracene lattice as a platform to investigate strong electronic correlations in the family of Kagome metal-organic frameworks. We show that the low-energy model is composed by molecular orbitals which arrange themselves in a typical Kagome lattice … Nettet17. mar. 2024 · At the outset, we note that there are profound differences in doping physics between band semiconductors such as Si and Mott semiconductors such as VO 2 ().In Si and related materials, aliovalent doping concentration in the order of parts per million is sufficient for repositioning the Fermi level or band edges for function, whereas in Mott …

NettetThe Mott concept of a metal-insulator transition (MIT) appears to be amongst the most important 20th-century physical theories [1-7], along with, e.g., the BCS model for superconductivity, since it concerns a rather fascinating and interest-provoking problem of condensed matter physics. However, interestingly enough, the well-known Mott criterion
