Secondary electron emission yields from MgO deposited on carbon nanotubes
- W. Yi, S. Yu, Jungmin Kim
- Physics
- 22 March 2001
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 upon…
Secondary electron emission from magnesium oxide on multiwalled carbon nanotubes
- Won-Seok Kim, W. Yi, Young Hee Lee
- Physics
- 30 July 2002
We have investigated effects of electric fields on the yield of secondary electron emission (SEE) from the primary electron bombardment on magnesium oxide (MgO) covering vertically grown multiwalled…
Double layer-coated carbon nanotubes: Field emission and secondary-electron emission properties under presence of intense electric field
- Jungwoo Lee, Jaehong Park, Kijo Sim, W. Yi
- Materials Science
- 20 March 2009
The authors measured the field emission (FE) and secondary-electron emission (SEE) of carbon nanotubes (CNTs) after coating with wide-band-gap materials, such as MgO and CsI. The FE was increased…
Enhanced charge collection and reduced recombination of CdS∕TiO2 quantum-dots sensitized solar cells in the presence of single-walled carbon nanotubes
