Possible role of oxygen monomers reordering in the photoinduced charge transfer in RBa2Cu3O6+x material
Апстракт
The model of photoassisted oxygen ordering assumes that the enhancement of the conducting properties of RBa2Cu3O6+x material during the light illumination, is the consequence of the CuOx plane oxygen atoms reordering into long chain fragments, which are known to be better hole dopants than the short ones. Some experimental results suggest that this process is performed mainly through the reaccomodation of the oxygen monomer units (isolated oxygen ions). In the present work concentration of oxygen monomers in the CuOx planes, which is assumed to be equal to the concentration of holes transferred out of the chain planes during the light illumination, is calculated as a function of oxygen content x, and delta T-c (photoinduced enhancement of the superconducting critical temperature T-c) was estimated for different oxygen concentrations. Numerically found values of the (delta T-c, are shown to be in good agreement with experimental findings. (C) 2011 Elsevier Ltd. All rights reserved.
