Organic gas adsorption on vacancy defect Germanene: A DFT study

"Organic gas adsorption on vacancy defect Germanene: A DFT study" show that acetone, toluene and propanol are physisorbed on germanene via van der Waals interactions. The physisorption of gas molecules on germanene opens a band gap at the Dirac point of germanene. Overall, the different adsorption behaviors of organic gas molecules on vacancy defected germanene provide a feasible way to exploit chemically modified vacancy defected germanene for a wide range of practical applications, such as gas sensors and spintronic devices.
