Silicene on Other Two-dimensional Materials: Formation of Heterostructure

An Ab Initio Study of Lithization of Two-Dimensional Silicon–Carbon Anode Material for Lithium-Ion Batteries

“…The fact is that the strong interaction of the metal with silicene spoils the electronic structure of this two-dimensional material. Various two-dimensional materials (h-BN, C-SiC, MoS 2 ) have been investigated as a substrate for silicene intended for the needs of the electronics [34][35][36]. The van der Waals interaction between silicene and such a substrate breaks the symmetry of the silicene sublattices, which results in a band gap opening.…”

The symmetry breaking phenomenon in 1,2,3-trioxolene and C2Y3Z2 (Z= O, S, Se, Te, Z= H, F) compounds: a pseudo Jahn−Teller origin study

“…[1][2][3][4][5] The ozonation mechanism first time were suggested by Criegee 6 and based on his mechanism, two intermediates with five-member ring structure were presented in ozonolysis reaction with unsaturated compounds. Those intermediate structures were confirmed through 17 O-NMR spectroscopy method 7 (See Figure 1).…”

“…13,14 Through folding of rings in heterocyclic compounds, symmetry breaking phenomenon has been reported in many studies and the instability of the ground state in planar configuration of those molecules and their coupling with excited states have been explained via PJTE theorem. [15][16][17][18][19][20][21][22][23][24][25][26][27] Restoring planarity in the systems that are puckered from their planar configurations due to the symmetry breaking phenomenon has been investigated through the PJTE. To do so, their planar configuration restores ether by coordinating two anions, cations, or rings up and down to the nonplanar systems [28][29][30] or influences the parameters of the PJTE instability by removing or adding electrons; 31 they show that symmetry breaking phenomenon is suppressed in the folded systems.…”

Recent Advances in Synthesis and Properties of Hybrid Halide Perovskites for Photovoltaics

“…The more the steps, the more the attention should be paid to the reactions in order to minimize the impurities. There are a number of methodologies for fabrication of high-efficiency perovskite solar cells, such as the solution-processed two-step method [ 10 , 64 , 65 ], solution-processed single-precursor, and anti-solvent method [ 21 , 37 , 66 ], solution-processed adduct method [ 25 , 67 , 68 ], vacuum deposition method [ 69 – 71 ], ceramic solid-state reaction [ 72 – 74 ], glycine–nitrate route [ 75 , 76 ], and sol-freeze-drying technique and combustion method [ 77 – 80 ]. Among them, the most promising method is the combustion method.…”
