Abstract Diamond’s superior carrier transport properties and unparalleled radiation tolerance make it an ideal material for alpha/neutron detection. High performing diamond detectors are already commercially available. However, even high quality single crystal can degrade after doses of radiation, resulting in a reduction mean free path. It is well known that reducing the collection distance, by decreasing detector electrode spacing, makes more tolerant path reduction, therefore resilient to...
A new facility to study the interaction of hydrogen isotopes with nuclear fusion-relevant first wall materials, and their retention release, has been produced. The allows for implanting a range gases into samples, including tritium. An accurate isotope effects, such as isotopic exchange in damaged microstructure, previously difficult due background signal light hydrogen. This capability will allow virtually free measurements using tritium deuterium. design build this are described...
Surface transfer-doping, involving hydrogen terminated diamond surfaces, has been an effective method for producing devices some years but suffered from poor device longevity and reproducibility. The emergence of metal oxides as encapsulant begun to change this situation. Here, HfO2 encapsulated surface transfer doped Schottky diodes with stable characteristics have demonstrated. Ideality factor barrier heights the did not vary considerably across extended periods use (up 39 days). showed...
