- ПубликацияОткрытый доступStructure and Technological Parameters’ Effect on MISFET-Based Hydrogen Sensors’ Characteristics(2023) Podlepetsky, B.; Samotaev, N.; Etrekova, M.; Litvinov, A.; Подлепецкий, Борис Иванович; Самотаев, Николай Николаевич; Этрекова, Майя Оразгельдыевна; Литвинов, Артур ВасильевичThe influence of structure and technological parameters (STPs) on the metrological characteristics of hydrogen sensors based on MISFETs has been investigated. Compact electrophysical and electrical models connecting the drain current, the voltage between the drain and the source and the voltage between the gate and the substrate with the technological parameters of the n-channel MISFET as a sensitive element of the hydrogen sensor are proposed in a general form. Unlike the majority of works, in which the hydrogen sensitivity of only the threshold voltage of the MISFET is investigated, the proposed models allow us to simulate the hydrogen sensitivity of gate voltages or drain currents in weak and strong inversion modes, taking into account changes in the MIS structure charges. A quantitative assessment of the effect of STPs on MISFET performances (conversion function, hydrogen sensitivity, gas concentration measurement errors, sensitivity threshold and operating range) is given for a MISFET with a Pd-Ta2O5-SiO2-Si structure. In the calculations, the parameters of the models obtained on the basis of the previous experimental results were used. It was shown how STPs and their technological variations, taking into account the electrical parameters, can affect the characteristics of MISFET-based hydrogen sensors. It is noted, in particular, that for MISFET with submicron two-layer gate insulators, the key influencing parameters are their type and thickness. Proposed approaches and compact refined models can be used to predict performances of MISFET-based gas analysis devices and micro-systems.

This method is based on detecting increase ammonia concentration in patient’s exhaled air after reception of carbamide water solution. The device’s stable operation is based on MIS-FE gas sensor’s high sensitivity to ammonia, sensor’s parameters stability as well as especially developed two channels gas sampling system.

O.; Литвинов, Артур Васильевич; Самотаев, Николай Николаевич; Этрекова, Майя Оразгельдыевна© 2019 Published under licence by IOP Publishing Ltd. It was shown the possibility of using MIS-sensors as detectors sensitive elements of the nitro-containing organic trace. The detection is carried out due to the nitro groups, formed during the reaction of pyrolysis of the nitro compounds molecules.
- ПубликацияОткрытый доступPrototype of nitro compound vapor and trace detector based on a capacitive MIS sensor(2020) Mikhailov, A.; Samotaev, N.; Litvinov, A.; Etrekova, M.; Oblov, K.; Filipchuk, D.; Самотаев, Николай Николаевич; Литвинов, Артур Васильевич; Этрекова, Майя Оразгельдыевна; Облов, Константин Юрьевич© 2020 by the authors. Licensee MDPI, Basel, Switzerland.A prototype of a nitro compound vapor and trace detector, which uses the pyrolysis method and a capacitive gas sensor based on the metal–insulator–semiconductor (MIS) structure type Pd–SiO2 –Si, was developed and manufactured. It was experimentally established that the detection limit of trinitrotoluene trace for the detector prototype is 1 × 10−9 g, which corresponds to concentration from 10−11 g/cm3 to 10−12 g/cm3. The prototype had a response time of no more than 30 s. The possibility of further improving the characteristics of the prototype detector by reducing the overall dimensions and increasing the sensitivity of the MIS sensors is shown.
- ПубликацияОткрытый доступDetection of Chlorine by field effect sensor(2019) Samotaev, N. N.; Litvinov, A. V.; Etrekova, M. O.; Самотаев, Николай Николаевич; Литвинов, Артур Васильевич; Этрекова, Майя Оразгельдыевна© Published under licence by IOP Publishing Ltd.The gas analytical system for chlorine gas measurement based on metal-insulator-semiconductor field effect (MIS FE) type sensor has been developed. High sensitivity of MIS FE sensor to chlorine allows measuring concentrations in the sub-ppb level and to be stable for overload hydrogen gas concentration typically present in industrial electrolysis application. With the pulse heating mode, the response and relaxation times of the MIS sensor are reduced by an order of magnitude which gives chance to use one for high precision environmental control.

The results obtained can be used in online monitoring systems and predicting the power transformers integral performance, in particular those that have been put into operation long ago, by tracking slow and invisible at the initial stage aging processes of current-carrying connections and structural elements.
- ПубликацияТолько метаданныеCluster Model of the Mechanism of Sensitivity of Gas Sensors Based on MIS Structures(2019) Litvinov, A. V.; Samotaev, N. N.; Etrekova, M. O.; Klishin, Y. A.; Korolev, N. A.; Литвинов, Артур Васильевич; Самотаев, Николай Николаевич; Этрекова, Майя Оразгельдыевна; Королев, Николай Анатольевич© 2019, Pleiades Publishing, Ltd.A cluster model of the mechanism of sensitivity to gases is proposed, according to which the change in the electric capacity of a MIS sensor under the action of gas is caused by a change in the dielectric constant of the metal — dielectric transition layer under the action of gas molecules. The dielectric constant of the transition layer changes due to the rearrangement of the electronic structure of the traps.
