Bismuth-based nanoribbons show ‘topological’ transport,potential for new technologies
Bismuth-based nanoribbons topological transport potential
2016/2/22
Researchers have created nanoribbons of an emerging class of materials called topological insulators and used a magnetic field to control their semiconductor properties, a step toward harnessing the t...
Single-Longitudinal-Mode Lanthanum-Codoped Bismuth-Based Erbium Doped Fiber Ring Laser
Single-Longitudinal-Mode Lanthanum-Codoped Bismuth-Based Erbium Doped Fiber
2015/7/16
We propose and demonstrate a stable single-longitudinal-mode lanthanum-codoped bismuth oxide-based erbium doped fiber ring laser. The combination of a free-space thin-film filter and a Lyot filter ena...
