Outline of Final Research Achievements |
In order to form a free-standing-like epitaxial silicene, and to form a capping layer which keeps the properties of silicene but prevents oxidation of silicene, the interfaces formed between silicene and substrates, silicene and capping layers were studied using high-resolution photoelectron spectroscopy at synchrotron radiation facility. By depositing silicon on zirconium diboride thin film terminated by monolayer hexagonal boron nitride (h-BN), silicene was formed in between h-BN and diboride. Photoelectron spectroscopy revealed that this silicene sheet formed through intercalation has similar electronic properties to the spontaneously formed ones, and monolayer h-BN successfully prevents oxidation of silicene for at least an hour in air.
