Light driven bunching of electrons in glasses: structuring of a matter by light

Light driven structuring of glasses

“…However in the region of strong electric field due to Franz-Keldysh effect [9], [10] this process becomes effective. Energy discrepancy δǫ between the glass gap and photon energy is gained from the static electric field in process of electron tunneling (the corresponding estimation see in [6]). So, domain boundaries due to strong electric field become a weak chain in glass bonds and light driven bond breaking (local fusion) reveals bunch structure of the self-organized stimulation of the process (such as plasma generation in the vicinity of a sample or specific UV absorbing medium [11]).…”

“…In main features it is the same for all dimensions. The corresponding model is presented in details in [5], [6], [7]. Computer simulation of the electron kinetics in the finite sample under external …”

“…In the latter case light amplitude has been modulated in time and space, which was crucial for the organization to occur. Our investigations(see [5], [6], [7] and references therein) have shown that steady light flow through a system can provide ordering either. This light is a driving force which bunches the electrons in the case in hand.…”

Self-organization driven by broad band light

“…The third electron is transported to the bielectron and so on. We observed this light driven bunching [6,7] under laser pumping in ablation due to Franz-Keldysh effect [12,13]. We found that for different light parameters-power, beam size, coherent length-ordered structure of electron-hole bunches with the same period is formed.…”

“…In the latter case light amplitude has been modulated in time and space, which was crucial for the organization to occur. Our investigations [5][6][7][8] have shown that steady light flow through a system can provide ordering either. This light is a driving force which bunches the electrons together.…”
