Silicon-vacancy color centers in Si- and Si,P-doped nanodiamonds: thermal susceptibilities of photo luminescence band at 740 nm
Sumin Choi, Viatcheslav N. Agafonov, Valery A. Davydov +2
We have characterized thermal susceptibilities of the spectral band at 740 nm of silicon-vacancy (SiV) centers in Si- and Si,P-doped nanodiamonds over a temperature range from 295…
Electrical excitation of silicon-vacancy centers in single crystal diamond
Amanuel M. Berhane, Sumin Choi, Hiromitsu Kato +4
Electrically driven emission from negatively charged silicon-vacancy, (SiV)- centres in single crystal diamond is demonstrated. The SiV centres were generated using ion implantatio…
Electroluminescence from isolated defects in zinc oxide, towards electrically triggered single photon sources at room temperature
Sumin Choi, Amanuel M. Berhane, Angus Gentle +3
Single photon sources are required for a wide range of applications in quantum information science, quantum cryptography and quantum communications. However, so far majority of roo…
