在ABX3晶体结构中，半径较大的A位阳离子位于八面体的八个顶点位置，半径较小的B位阳离子位于八面体的体心位置，X位阴离子位于八面体的面心位置。其中A位是一价阳离子，一般为铯离子（Cs+）、甲胺离子（CH3(NH）2+，MA+）和甲脒离子（HC(NH2)2+，FA+）等，A位离子主要补偿晶格电荷，调节钙钛矿能带，从...
A fully relaxed potential energy scan revealed the stability of the possible conformers of this molecule. We present the density functional theory results and assignment of the vibrational modes in the infrared spectrum. The experimental and scaled simulated vibrations matched when density functional ...

Figure 3. Analysis of A-XRD difference patterns for P50 (upper panels) and P75 (lower panels) samples at Au (left) and Pd (right) edges. The experimental points (red dots) and the best fit line (black line) are shown together, with peaks corresponding to the bimetallic phases A (orang...
As seen in Figure 1a, the XRD scan at 600 °C shows the emergence of a new peak at a 2θ value of 43.25° which indicates the initiation of the FCC phase, shown by green dots. As the temperature rises to 650 °C, additional peaks were observed at 2θ values of 45.32°, 46.41°...
