Abstract
We investigated the physical mechanism of dynamical bond formation, light-created defect centers and light induced electron spin resonance for Se chains and a realistic model of amorphous selenium by ab-inito molecular dynamic simulation. It is found that the Coloumb interaction between light-created charge centers plays the key role in the bond breaking, switching and reconstruction in Se chain and a-Se under the light irradiation.
