A model of generation and dynamics of radiation conductivity in quartz under the action of powerful soft X-ray radiation is constructed. The charge carrier dynamics model is based on the joint solution of self-consistent kinetic equations and Maxwell's equations. The model was verified by comparing the current calculations on the quartz surface with experiments on the Angara-5-1 thermonuclear installation. The current over the surface of the quartz sensor generated by a powerful pulse of soft X-ray radiation from the Angara-5-1 setup was taken as experimental data.

Charge-carrier transfer (CT) from the perovskite host to PbS QDs were studied using fs-transient absorption and THz techniques. The CT rate constants increase with the size of QDs due to a change in the position of valence and conduction bands in PbS QDs.
