Моделирование реакции низкобарьерного диода Мотта на воздействие тяжелых заряженных частиц космического пространства

A theoretical analysis of transient ionization processes occurring in a low-barrier GaAs Mott diode under the influence of space radiation high energy charged particles and simulating pulsed laser radiation is carried out. The diode response to the As+ ion action with an energy of 200 MeV, corresponding to a linear energy transfer of 26 MeV cm2/mg, is compared with the response to the femtosecond pulses optical radiation action of various durations (10-1000 fs) and photon energies exceeding the GaAs band gap.

Samoylov, L.V. Levash, O.A. Rosnovskiy, M.Yu. Vedula, V.S. Rad'ko Institute of Physics, NAS of Ukraine, 46, prospect Nauky, 03680 Kyiv, Ukraine E-mail: [email protected] Abstract. The general arrangement, principle of operation and basic parameters of pyroelectric USB-meters of energy of pulsed laser radiation have been described. A smart head of the meter converts the signal from the pyroelectric sensor and immediately transfers it to PC using a high-speed USB 2.0 connection. The device consists of two circuit panels located in the common package. The pyroelectric sensitive element and preamplifier are mounted on the sensor panel. Output of the preamplifier is connected with input of the preliminary digital processing panel. The meter is connected with host computer that performs further processing, storage and monitoring of data. Sensor panel can be produced in two modifications, dependently on the pulse energy. Sensitive elements on the base of LiNbO3 or LiTaO3 with absorbing coatings are used for measuring the low-energy pulses, whereas the transparent sensitive elements with a small intrinsic absorption is used for measurements of high-energy radiation pulses. The pulse rate and pulse energy can vary from single pulses up to 2 kHz and from 0.1 μJ up to 0.5 J, respectively. Keywords: laser, impulse radiation, joulemeter, detector, pyroelectric.

A theoretical analysis of the degradation of the current-voltage characteristic and transient ionization processes occurring in a low-barrier uncooled GaAs Mott diode under the action of heavy ions of outer space and laser pulses simulating them is carried out. The response of the diode to the action of an arsenic ion with an energy of 200 MeV, corresponding to a linear energy transfer of 26 MeV∙cm2/mg, is compared with the response to the action of femtosecond pulses of optical radiation with a duration of 10 fs with a wavelength of 870 nm and 670 nm.
