Their remarkable properties are underpinned by atomic struc- tures of hybrid perovskites7, ABX3, with organic species such as CH3NH3+ (MA+) and CH(NH2)2+ (FA+) occupying A-site and inorganic Pb2+ in B-site surrounded by X-octahedron formed by halogen elements like I− and Br−. ...
The electrochemical quartz crystal microbalance (EQCM) is a technique that monitors the mass of the working electrode as a function of time: the test material is deposited on a thin quartz crystal wafer, the resonance frequency of which, under optimum conditions, is inversely proportional to...
It has also been validated that the MOFs prepared with this method are almost the same as those synthesized with the conventional ones, in terms of both micro-structures and optical properties [36]. It was further found that the FL intensity of the UiO-66-NH2 increased in a linear manner ...
The formation carrier mass and alteration of electronic structures in these of ripples 2D mate- rials. Buckling and ripple formation has also been predicted using molecular dynamics (MD) simulations under uniaxial compression27. The size of the ripples generated during compression is observed to be ...
Compared with top-down exfoliation, bottom-up vapor deposition has the advantages of mass production of 2D materials and high-quality control [65]. Table 1 summarizes some major ALD process parameters and applications. Table 1. ALD for some common materials. To date, the application of ALD ...
The NH and NH2 radicals contribute to the growth of GaN films while the H radicals selectively dissociate Ga-OH bonds on the film surface and etch the grown films. At high plasma power, the GaN film with the lowest Ga-O bond ratio has a saturated growth rate, a better crystallinity, a...
