Today, scientists have discovered a new phenomenon of surface diffusion of ions in two-dimensional channels. This phenomenon is observed when ions are confined to a two-dimensional channel, and the surface of the channel is exposed to a potential gradient. This surface diffusion causes the ions to move along the surface of the channel, rather than through the channel itself. This phenomenon could have important implications for the development of advanced nanoscale devices. By understanding how ions move through two-dimensional channels, scientists may be able to develop devices that can control the motion of ions with unprecedented precision.
