Diamond and zinc oxide are both wide-band gap materials exhibiting physical and chemical properties that make them particularly attractive for applications in optoelectronic devices. Intentionally-introduced impurities, called dopants, can render these materials semiconducting, determine whether the current is carried by electrons or holes and, ultimately, how information is processed by, for example, an optoelectronic device. However, due to the nature of these two materials, achieving efficient bi-polar (n- and p-type) doping to form p-n junction devices remains a challenge. Characterisation tools at Bristol are used to optimise the growth of high-quality doped materials. Both materials can be synthesized in the form of single crystal nanoparticles. These, potentially, can exhibit properties not attainable with the respective bulk materials. Recent and current Bristol-based research has demonstrated growth of intrinsic diamond and zinc oxide nanoparticles, with low impurity content and a low density of structural defects.
