A unique nanoheterostructure, a boron-filled hybrid carbon nanotube (BHCNT), has been synthesized using a one-step chemical vapor deposition process. The BHCNTs can be considered to be a novel form of boron carbide consisting of boron doped, distorted multiwalled carbon nanotubes (MWCNTs) encapsulating boron nanowires. These MWCNTs were found to be… (More)
We demonstrate high-fidelity transfer of the polarisation of a photon into the spin-state of an electron-hole pair. Spins are then electrically manipulated on sub-nanosecond timescales and near-unity phase-shift and spin-flip gate operations are demonstrated.
