The song, by the then-Tottenham Hotspur and England teammates, reached number 12 in the UK Singles Chart in May 1987 and was by far the more successful of two chart releases for the duo. Despite its success, public opinion of the record's quality has been decidedly negative with the pair's television performance of the song being widely ridiculed. Chris Waddle recalls the single coming about following an appearance two of them made for their personal sponsors, Budget
Germanium-vacancy center in diamond Germanium-vacancy center in diamond The germanium-vacancy center (Ge-V) is an optically active defect in diamond, which can be created by doping germanium into diamond during its growth or by implanting germanium ions into diamond after its growth. Its properties are similar to those of the silicon-vacancy center in diamond (SiV). Ge-V can behave as a single-photon source and shows potential for quantum and nanoscience applications due to its narrow zero-phonon line (ZPL) and minimal phononic-sideband (compared to that of the nitrogen-vacancy center (NV). Ge-V is predicted to consist of one germanium atom situated between two adjacent lattice vacancies and have
