The Grey Zone in Doping
Anti-doping programs seek to preserve what is intrinsically valuable about sport. This intrinsic value is often referred to as “the spirit of sport”, which is the celebration of the human spirit, body and mind and is characterised by values such as ethics, fair play, honesty, health, fun, team …

Doping Studies of Frustrated Magnets
Doping nonmagnetic materials is known as an effective way of investigating the properties of frustrated magnets. LiCuSbO4 is one of the simplest quasi-one dimensional spin-1/2 magnets which can be modelled with ferromagnetic(FM) nearest neighbour and antiferromagnetic (AFM) next nearest neighbour …

Coating and Doping of Ge QDs
… particularly solar applications. Unlike doping of traditional bulk semiconductors materials, the location of the doping element can be either within the crystal lattice (c-doping), on the surface (s-doping), or within the surrounding matrix (m-doping). A range of attempts to dope Ge QDs …

Doping of group IV semiconductor nanowires
… literature to date has reported solution-based doping of VLS grown Ge or GeSn NWs. This thesis reports liquid-phase VLS growth and in-situ doping of Ge and GeSn NWs using a variety of dopant precursors. SEM and TEM were used to analyse the morphology of NWs grown. TEM, XRD and Raman Spectroscopy …

Continuos Doping of La2CuO4+x Thin Films
Finding more efficient ways of exploring the doping phase diagrams of high temperature superconductors as well as probing the fundamental properties of these materials are essential ingredients for driving the discovery of new materials. We use a doping technique involving gating with ionic liquids …
