This study addresses the ongoing debate concerning the distribution of indium in InxGa1−xN quantum wells(QWs) using a combination of atom probe tomography (APT) and transmission electron microscopy(TEM). APT analysis of InxGa1−xN QWs, which had been exposed to the electron beam in a TEM, revealed an inhomogeneous indium distribution which was not observed in a control sample which had not been exposed to the electron beam. These data validate the effectiveness of APT in detecting subtle compositional inhomogeneities in the nitrides.

Rationale, design and methods for a randomised and controlled trial to investigate whether home access to electronic games decreases children's physical activityStraker, Leon; Abbott, R.; Piek, Jan; Pollock, Clare; Davies, P.; Smith, Anne (2009)Background: Many children are reported to have insufficient physical activity (PA) placing them at greater risk of poor health outcomes. Participating in sedentary activities such as playing electronic games is widely ...
To remove or to replace traditional electronic games? A crossover randomised controlled trial on the impact of removing or replacing home access to electronic games on physical activity and sedentary behaviour in children aged 10-12 years.Straker, Leon; Abbott, R.; Smith, Anne (2013)Objective: To evaluate the impact of (1) the removal of home access to traditional electronic games or (2) their replacement with active input electronic games, on daily physical activity and sedentary behaviour in children ...
Effects of home access to active videogames on child self-esteem, enjoyment of physical activity, and anxiety related to electronic games: results from a randomized controlled trialAbbott, R.; Smith, Anne; Howie, Erin; Pollock, Clare; Straker, Leon (2014)Objective: Active-input videogames could provide a useful conduit for increasing physical activity by improving a child’s self-confidence, physical activity enjoyment, and reducing anxiety. Therefore this study evaluated ...
