By field Using AND/OR By author
This tool can help you build boolean queries suitable for doing a broad search for different synonyms or spellings of each word. Start via the drop-down below or just start typing in the search field.
{{ row.typeTitle }}: ( )

Since our index often lack the full first name of people it can be difficult to correctly search by author.

Fill in the fields and let us help you build a good query:

If you need to find everything possible, consider only searching by last name.

Use "Starting year" to ignore publications out of year range.

Characterization of donor-acceptor-pair emission in fluorescent 6H-SiC

Ou, Yiyu; Jokubavicius, Valdas; Linnarsson, Margareta; Yakimova, Rositza; Syvajarvi, Mikael; Ou, Haiyan

Physica Scripta — 2012, Volume 2012, Issue T148, pp. 014003

We investigated donor-acceptor-pair emission in N-B-doped 6H-SiC samples by using photoluminescence (PL) and angle-resolved PL. It is shown that n-type doping with concentrations larger than 10(18) cm(-3) is favorable for observing luminescence, and increasing nitrogen results in stronger

Characterization of donor-acceptor-pair emission in fluorescent 6H-SiC

Ou, Yiyu; Jokubavicius, Valdas; Linnarsson, Margareta; Yakimova, Rositza; Syväjärvi, Mikael; Ou, Haiyan

shifts with increasing emission angle in sample #d, and the FWHM starts to decrese and becomes more dramatic when the emission angle is larger than 45 degrees. Our results revealed that the optimized way to achieve intense DAP emission in B-N-doped 6H-SiC is to use low-level n-type doping with both B
