Crystal lattice chemistry
WebCrystal lattice is a symmetrical three-dimensional structural arrangement of atoms, ions or molecules (constituent particles) inside a crystalline solid as points. There are seven types of unit cells: Cubic, Tetragonal, Orthorhombic, Monoclinic, Hexagonal, Rhombohedral or Trigonal and Triclinic. Web1 day ago · The nanoscale moiré pattern formed at 2D transition-metal dichalcogenide crystal (TMDC) heterostructures provides periodic trapping sites for excitons, which is essential for realizing various exotic phases such as artificial exciton lattices, Bose–Einstein condensates, and exciton insulators. At organic molecule/TMDC heterostructures, similar …
