A Thermodynamic Perspective for Formation of Solid Electrolyte Interphase in Lithium-Ion Batteries

In Situ Growth Mechanism for High‐Quality Hybrid Perovskite Single‐Crystal Thin Films with High Area to Thickness Ratio: Looking for the Sweet Spot

“…Consider the nucleation of a MAPbBr 3 crystal nucleus in an n-sided (n = 4 in this work), regular polygon in the sandwiched structure shown in Figure 1a. Assuming that the thickness of the crystal film is h and the side-length is a, and only one surface of the MAPbBr 3 SCTF is in contact with the HTL (Figure 1b), the difference of the Gibbs free energies, ΔG, [50] can be expressed as (12) Under the condition that the volume of the MAPbBr 3 crystal nucleus is constant, the minimum interface energy between MAPbBr 3 SCTF and HTL yields…”
