Secondary electron emission yields from MgO deposited on carbon nanotubes
Enormously high secondary electron emission yields under electric field are observed from MgO deposited on carbon nanotubes. The yields reach a value as high as 15 000 and are strongly dependent uponExpand

Transfer matrix method for interface optical-phonon modes in multiple-interface heterostructure systems
Interactions of carriers with interface optical phonons dominate over other carrier–phonon scatterings in narrow quantum-well structures. Herein, a transfer matrix method is used to establish aExpand
