Diamane Oxide. Two-Dimensional Film with Mixed Coverage and a Variety of Electronic Properties

Here, we investigate stability of the diamane oxide films and show that various compositions can be realized depending on the precursors, temperature, and pressure. We demonstrate that the commonly used oxygen source in the H2O form requires pressures of GPa order to fabricate the film, which is in full agreement with the experimental data. We show that different types of functional groups can tailor electronic properties of bilayer diamane. Finally, we study electronic property dependence on the film thickness, elucidating its connection with surface states.

Automated summary

In this study, we investigated the stability of diamane oxide films and found that their composition can vary depending on the precursors, temperature, and pressure. Our findings supported the experimental data by showing that high pressures are required to fabricate the films using the commonly used oxygen source in the form of H2O. Additionally, we demonstrated that different functional groups can modify the electronic properties of bilayer diamane. Furthermore, our study explored the relationship between the film thickness and electronic properties, specifically surface states.
