WebSnO is lead oxide structured and crystallizes in the tetragonal P4/nmm space group. The structure is two-dimensional and consists of one SnO sheet oriented in the (0, 0, 1) direction. Sn²⁺ is bonded in a 4-coordinate geometry to four equivalent O²⁻ atoms. All Sn–O bond lengths are 2.23 Å. O²⁻ is bonded to four equivalent Sn²⁺ atoms to form a mixture of edge … WebThe concept of mixed 2D/3D heterostructures has emerged as an effective method for improving the stability of lead halide perovskite solar cells, which has been, however, rarely reported in lead–tin (Pb–Sn) mixed perovskite devices. Here, we report a scalable process for depositing mixed 2D/3D Pb–Sn perovskite solar cells that deliver remarkably …

Tin is a chemical element with the symbol Sn (from Latin: stannum) and atomic number 50. Tin is a silvery-coloured metal. Tin is soft enough to be cut with little force and a bar of tin can be bent by hand with little effort. When bent, the so-called "tin cry" can be heard as a result of twinning in tin crystals; this trait is shared by indium, cadmium, zinc, and mercury in … WebEven more crystal 'about' info on the collection pages mentioned above as well.
