By comparison, more delocalized ionic bonding takes place between Fe3+ and Ge/Te ions. This difference between localized and delocalized electron distributions around the Fe3+ and Fe2+ ions is also supported by deformation charge density analysis and Bader charge (see Supplementary Fig. 2 and ...
We will first explain the mechanism of photodetection by using a simple Schottky diode photodetector as an example which will later help to understand the contribution of plasmonic structures. Considering a Schottky diode is more instructive to describe two different photodetection mechanisms. In this ex...

How to determine orbital hybridization Draw the electron dot diagram for the CCl_2 molecule and determine its VSEPR shape. How to determine bond order from molecular electron configuration Draw the electron dot diagram for the CH_3^- molecule and determine its VSEPR shape. Explain bonding in term...
The description of structure and bonding in solids given in the preceding sections is largely qualitative, but it is a fair (although abbreviated) account of most of what was generally known as a result of quantum mechanical analysis in the period from 1930 to 1960. Starting in 1960 a more ...
