Time-domain impedance method for transient photovoltage analysis

Autor: Nadtochiy, A., Podolian, A., Korotchenkov, O.

In this work, we approximate the surface photovoltage (SPV) transients in nm-sized ZnO films by the equivalent RC circuit model. The SPV rises in time in time for about 90 mcs after the exciting light pulse at 275 nm is off at different pulse widths

Variational computation of a vibrating lithium niobate rectangular plate

Autor: Polovina, O. I., Kurylyuk, V. V., Korotchenkov, O. A.

Electrically-excited electroelastic extensional vibrations of an arbitrarily cut three-dimensional piezocrystal resonator are analyzed variationally. A set of trigonometric trial functions applicable to a waveguide behavior of the resonator partly co

Alteration of Domain Microstructure by Ultrasound In Lithium Niobate

Autor: Ostrovskii, I. V., Borovoy, N. O., Korotchenkov, O. A., Nadtochii, A. B., Chupryna, R. G.

A reorientation of the ferroelectric domains under an action of ultrasound in LiNbO3 is observed for the first time. The involvement of the ferroelectric domain boundaries is experimentally identified by the analysis of X-ray reflection and crystal e
