An analog computation of charges and holes mobility is carried out based on the structure of amorphous system by Monte Carlo and master equation. The conclusion shows that mobility of holes is higher than charges by these two methods without the consideration of polarized locus energy in the structure of UFF force field analog. However, mobility of charges following the increase of electric field will be higher than holes if we take polarized locus energy into consideration. This fits the behavior of Poole-Frenkel. In the structure of Dreiding force field analog, the mobility is equal by two methods without polarized locus energy. If considerate, mobility of holes is higher than charges which may be the reason of a higher transfer integration of holes than charges (stronger coupling) with a deeper electron trap. This means that accumulation may be the key point of ensuring the transmittability of substance carriers. Soon after that we conclude that there’s nothing different among variation tendency of dynamic transfer integration of charges from 1ps to 100ps. So we can calculate long-term transfer integration of charges by the short-term. |
