This paper introduces a metalloid source/drain Gate All Around (GAA) FET for detection of poisonous gas such as Chloroform (CHCl3), Dichloromethane (CH2Cl2), Iso-propanol (Iso-C3H7OH), Methanol (CH3OH), Hexane (C6H14) exists in the atmosphere. The conducting polymer (P-polyphenylene) based source, drain and gate electrodes are utilized for detection of these poisonous gases. The modulation in electrostatics parameter of proposed gas sensor based on work function modulation of these conductive polymer (CP) electrodes is the basic principle of poisonous gas detection. Threshold voltage and drain current sensitivities of this gas sensor have been investigated for detection of poisonous gases. Chloroform (CHCl3) exhibits highest threshold voltage and drain current sensitivities of 1.15 × 104% and 23% respectively among other poisonous gases. Optimization of radius and channel length of this gas sensor is also performed to achieve superior sensing performance. Effect of temperature variation on drain current is also investigated for better performance of the proposed sensor.

摘要

This paper introduces a metalloid source/drain Gate All Around (GAA) FET for detection of poisonous gas such as Chloroform (CHCl3), Dichloromethane (CH2Cl2), Iso-propanol (Iso-C3H7OH), Methanol (CH3OH), Hexane (C6H14) exists in the atmosphere. The conducting polymer (P-polyphenylene) based source, drain and gate electrodes are utilized for detection of these poisonous gases. The modulation in electrostatics parameter of proposed gas sensor based on work function modulation of these conductive polymer (CP) electrodes is the basic principle of poisonous gas detection. Threshold voltage and drain current sensitivities of this gas sensor have been investigated for detection of poisonous gases. Chloroform (CHCl3) exhibits highest threshold voltage and drain current sensitivities of 1.15 × 104% and 23% respectively among other poisonous gases. Optimization of radius and channel length of this gas sensor is also performed to achieve superior sensing performance. Effect of temperature variation on drain current is also investigated for better performance of the proposed sensor.
