WebMay 8, 2012 · The Mott-Anderson transition has been known as a metal-insulator (MI) transition due to both strong electron-electron interaction and randomness of the electrons. For example, the MI transition in doped semiconductors and transition metal oxides has been investigated up to now as a typical example of the Mott-Anderson transition for … WebFeb 1, 2024 · Sorted by: 1. This is the triboelectric effect. One microscopic explanation is that when you rub two insulating materials the different atoms get close enough that it is energetically favourable for them to exchange electrons. Then when you pull them apart the electrons stay put and the objects both have a net charge (one positive, one negative). short morning prayer quotes https://flowingrivermartialart.com
