^Bond angle variations in XH3 [X = N, P, As, Sb, Bi]: the critical role of Rydberg orbi...
Structural study of bond length, bond angle and bond distortion increases slightly with increase in the surface passivation. From PDOS there is merely an equivalent contribution to the surface states from ZnO and NH3 molecules except for 3 NH3 capping where contribution of ZnO is very less. ...
(TEM-EDX) and SAED were carried out on a Tecani G2 F20 instrument at an accelerating voltage of 200 KV. SEM and SEM-EDX spectroscopy were performed on a Hitachi S-4700 cold field emission scanning electron microscope operated at 30 KV. The powder wide angle X-ray diffraction pattern (...
The FM interaction is the consequence of the strongly distorted orthorhombic perovskite structure with Mn–I–Mn bond angle significantly reduced to B150° (Fig. 2c,d). Melting ferromagnetic order by photoelectrons. Our major finding is a striking change of the magnetism when the sample is ...
Tetragonal perovskite structure of methyl-ammonium metal iodide CH3NH3MI3 (M=Sn, Pb) was investigated, with space group of #99 with P4mm, lattice parameter of a = b = 6.6718, c = 6.4101, bond angle of α = β = γ = 90. The electronic st... G Tse,D Yu 被引量: 3发表: 2015...

How Strong Is the Hydrogen Bond in Hybrid Perovskites? Hybrid organic–inorganic perovskites represent a special class of metal–organic framework where a molecular cation is encased in an anionic cage. The molecule–cage interaction influences phase stability, phase transformations, and the... KL Sva...
Mn2+impurities substituting Pb2+ions do not give rise to charge-carrier doping and do not induce any mid-gap states (Fig. 2b). The FM interaction is the consequence of the strongly distorted orthorhombic perovskite structure with Mn–I–Mn bond angle significantly reduced to∼150° (Fig. 2...
(TC), and thermal decomposition temperature (Td113C magic angle spinning (MAS) nuclear magnetic resonance (NMR) method plays a crucial role in understanding local dynamics. Determining the spin–lattice relaxation times T1ρfor1H and13C is essential for studying dynamical processes. By analyzing ...
