Abstract

Evolution of the microwave-probed photoconductivity transients and of the proton induced luminescence has simultaneously been examined in polycrystalline CdS layers evaporated in vacuum during exposure to a 1.6MeV proton beam. The decrease of the intensity of luminescence peaked at 510 and 709 nm wavelengths and of values of the effective carrier lifetime has been correlated in dependence of proton irradiation fluence. The defect introduction rate has been evaluated by the comparative analysis of the laser and proton beam induced luminescence. The difference of a carrier pair generation mechanism inherent for light and for a proton beam has been revealed. [ABSTRACT FROM AUTHOR]

31. Microwave resonant dielectric dispersion in SbS0.7Se0.3I crystals

Author

Kalesinskas, V., Grigas, J., Audzionis, A., and ZlCkus, K.

Abstract

Microwave dielectric investigations of SbS0.7Se0.3 I crystals were carried out over the frequency range 9 to 80 GHz. The main resonant dielectric dispersion caused by the soft mode occurs in the microwave range. On approaching the Curie point, the frequency of the microwave soft mode varies according to v2r = A(T - T0) with A = 1.1 × 1020 Hz2. K-1 and T0= 189 K in the symmetric phase, and with A = -3 × 1020Hz2. K-1 and T0 = 193 K in the ferroelectric phase. The soft microwave mode does not belong to the set of normal modes. The phase transition is intermediate between the pure displacive and order-disorder types.

32. Microwave study of the soft ferroelectric mode in Sn2P2S6 crystals

Author

Grigas, J., Kalesinskas, V., Lapinskas, S., and Gurzan, M. I.

Abstract

This paper presents the results of the investigation of dielectric dispersion in semiconductive ferroelectric Sn2P2S6 crystals over the frequency range 1 kHz to 78.5 GHz. The main dielectric dispersion in Sn2P2S6 is caused by the soft ferroelectric Bu mode and in the vicinity of the Curie point it occurs in the millimeter region. The frequency of the soft mode in the paraelectric phase varies according to vs = 35 (T-Tc)½ GHz on approaching the Curie point. The soft mode is strongly overdamped. Close to Tc the relative damping is y/vs = 14. The dielectric contribution of the soft mode is equal to the static dielectric permittivity and it explains its whole temperature-dependence.

44. Simulations of operation dynamics of different type GaN particle sensors.

Author

Gaubas E, Ceponis T, Kalesinskas V, Pavlov J, and Vysniauskas J

Abstract

The operation dynamics of the capacitor-type and PIN diode type detectors based on GaN have been simulated using the dynamic and drift-diffusion models. The drift-diffusion current simulations have been implemented by employing the software package Synopsys TCAD Sentaurus. The monopolar and bipolar drift regimes have been analyzed by using dynamic models based on the Shockley-Ramo theorem. The carrier multiplication processes determined by impact ionization have been considered in order to compensate carrier lifetime reduction due to introduction of radiation defects into GaN detector material.

Abstract

The problem of drifting charge-induced currents is considered in order to predict the pulsed operational characteristics in photo-and particle-detectors with a junction controlled active area. The direct analysis of the field changes induced by drifting charge in the abrupt junction devices with a plane-parallel geometry of finite area electrodes is presented. The problem is solved using the one-dimensional approach. The models of the formation of the induced pulsed currents have been analyzed for the regimes of partial and full depletion. The obtained solutions for the current density contain expressions of a velocity field dependence on the applied voltage, location of the injected surface charge domain and carrier capture parameters. The drift component of this current coincides with Ramo's expression. It has been illustrated, that the synchronous action of carrier drift, trapping, generation and diffusion can lead to a vast variety of possible current pulse waveforms. Experimental illustrations of the current pulse variations determined by either the rather small or large carrier density within the photo-injected charge domain are presented, based on a study of Si detectors.
