Hopping Conductivity - an overview ScienceDirect Topics

Crystalline solids and molecular solids are two opposite extreme cases of materials that exhibit substantially different transport mechanisms. While in atomic solids transport is intra-molecular, also known as band transport, in molecular solids the transport is inter-molecular, also known as hopping transport. The two different mechanisms result in different charge mobilities. In disordered solids, disordered potentials result in weak localization effects (traps), which reduc… Web4 feb. 2024 · We have found that the mechanism of hydrogen ion conduction is related to the index of acid and alkali.
