Half-filled intermediate bands Si material formed by energetically metastable interstitial sulfur atom
Ke-Fan Wang, Mingguo Liu, Yaping Ma +3
Hyperdoped metastable sulfur atoms endow crystalline silicon with a strong sub-bandgap light absorption. In order to explore such metastable states, we develop a new high-throughpu…

Nearly Free Electron States in Graphene Nanoribbon Superlattices
Shuanglin Hu, Zhenyu Li, Qiaohong Liu +3
Nearly free electron (NFE) state is an important kind of unoccupied state in low dimensional systems. Although it is intensively studied, a clear picture on its physical origin and…
