Characterization of B-implanted 3C-SiC for intermediate band solar cells

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1503792

Sublimation-grown 3C-SiC crystals were implanted with B ions at elevated temperature (400 °C) using multiple energies (100 to 575 keV) with a total dose of 1.3×1017 atoms/cm2 in order to form intermediate band (IB) in 3C-SiC. The samples were then annealed at 1400 °C for 60 min. An anomalous area in...

Structural and physical characteristics of fine perlite expanded with a novel method in a vertical electric furnace

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1451262

Expanded perlite is a popular lightweight material widely used due to its outstanding insulating properties. The expansion conditions directly affect perlite characteristics and its suitability for use in various applications. The conventional industrial expansion technique suffers disadvantages tha...

Cubic silicon carbide as a potential photovoltaic material

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1308673

In this work we present a significant advancement in cubic silicon carbide (3C-SiC) growth in terms of crystal quality and domain size, and indicate its potential use in photovoltaics. To date, the use of 3C-SiC for photovoltaics has not been considered due to the band gap of 2.3 eV being too large ...

Boron-implanted 3C-SiC for intermediate band solar cells

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1308759

Sublimation-grown 3C-SiC crystals were implanted with 2 atomic percent of boron ions at elevated temperature (400 °C) using multiple energies (100 to 575 keV) with a total dose of 8.5×1016 atoms/cm2. The samples were then annealed at 1400, 1500 and 1600 °C for 1h at each temperature. The buried boro...

Structural properties of Cu2O epitaxial films grown on c-axis single crystal ZnO by magnetron sputtering

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1368150

Epitaxial Cu2O films grown by reactive and ceramic radio frequency magnetron sputtering on single crystalline ZnO (0001) substrates are investigated. The films are grown on both O- and Zn-polar surface of the ZnO substrates. The Cu2O films exhibit a columnar growth manner apart from a ∼5 nm thick Cu...

Aluminium substituted lanthanum based perovskite type oxides, non-stoichiometry and performance in methane partial oxidation by framework oxygen

https://www.sintef.no/publikasjoner/publikasjon/?pubid=CRIStin+1368329

A series of Rh-promoted La0.75Sr0.25(Fe0.80Co0.20)(1-x)AlxO3-δ (x = 0, 0.10, 0.25, 0.40, 0.60) samples were investigated as oxygen reservoirs for the conversion of CH4 to syngas at 873 K and 1 atm. Neutron powder diffraction studies revealed a decreasing rhombohedral distortion on increasing Al-cont...
