Improvement in the Selectivity of Semiconducting Resistive-type NO₂Sensors Linked with Calorimetric Hydrocarbon Sensors

Abstract

We construct a kink solution on a non-BPS D-brane using Berkovits' formulation of superstring field theory in the level truncation scheme. The tension of the kink reproduces 95% of the expected BPS D-brane tension. We also find a lump-like solution which is interpreted as a kink-antikink pair, and investigate some of its properties. These results may be considered as successful tests of Berkovits' superstring field theory combined with the modified level truncation scheme.

Promotion of NO2 Sensing Performance with Ag Modified DDT/Au/GaAs-Based Schottky Diode

“…Generally, good gas sensors are considered to exhibit properties of high sensitivity, good selectivity, portability, ease of preparation, low cost, and low power consumption. From reported research, many types of sensing devices are used in gas sensors, i.e., electrochemical, [7][8][9][10][11][12][13][14][15] chemiresistive-type [16][17][18][19][20][21][22][23][24][25] and Schottky-type devices. [26][27][28][29][30] The electrochemical sensor are based on the solidelectrolyte with metal oxide working electrode.…”

“…[26][27][28][29][30] The electrochemical sensor are based on the solidelectrolyte with metal oxide working electrode. [12][13][14][15] The chemiresistive-type of gas sensors have mainly been based on metal oxides, such as SnO 2 , 19,20 ZnO, 21,22 WO 3 , 23,24 and Fe 2 O 3 . 25 On the other hand, semiconductor materials including n-Si, 26 InP, 27 Si/Al, 28 InGaP, 29 and GaAs 30 have been used in Schottky-type gas sensors.…”
