Performance of bilayer carbon-doped boron nitride nanoribbon for gas sensing application

Abstract

Carbon doped Boron Nitride Nanoribbon (BC2NNR) materials is studied to expand its possibility for use sensing devices. In this paper, a bilayer Carbon doped Boron Nitride Nanoribbon hydrogen gas sensing performance is investigated using computational simulation at different temperature. The current - voltage characteristic was simulated from the device model evaluating the position of the hydrogen molecules on the bilayer BC2NNR surface namely on top of carbon, boron and both boron and nitrogen molecules. Through simulation, higher sensitivity was achieved when hydrogen molecules were attached to boron atom where considerable current variation was seen while the other two position exhibit little changes. The increment of temperature exhibits significant changes when the temperature was increasing double from the room temperature. Notable increase of more than 90% was obtained at a much higher temperature where significant increase in current was obtained in terms of sensitivity upon the attachment of Hydrogen molecules on boron binding site on bilayer BC2NNR. The results presented in this paper provides additional evident in applying bilayer BC2NNR for sensing application.
