sf 6 device Hi-pot

Mar 25, 2020 · The adsorption performance of Pd–BN monolayer upon SF 6 decomposed species is in order as SOF 2 SO 2 SO 2 F 2, with E ad of 0.94, 0.83 and 0.48 eV, respectively. After gas adsorption, the bandgap of Pd–BN monolayer is remarkably changed, making it possible for use of a resistance-type gas sensor.
