Dynamic properties of high-Tc superconducting nano-junctions made with a focused helium ion beam
Published 2021“…At lower temperature and for the highest He irradiation dose, the shot noise contribution must also be taken into account when approaching the tunneling regime. We conclude that these Josephson nano-junctions present the lowest noise level possible, which makes them very promising for future applications in the microwave and terahertz regimes.…”

Solution processed transition metal oxides selective contacts for Si heterojunction solar cells
Published 2021“…Most importantly, the carrier selectivity of TMOs is believed to be originated from oxygen vacancies related traps, through which carriers are extracted or transported through trap assisted tunnelling across the TMO and Si heterojunction. It has been reported that TMO/a-Si(i)/n-Si HSCs passivated with an a-Si:H layer have efficiency of 22.5 % with improved current performance, which is comparable to typical HIT cells with configuration of a-Si(p)/a-Si(i)/n-Si. …”
