We investigated the photoluminescence (PL) properties of regularly arranged N-polar InN microcrystals with m -plane sidewall facets. We observed narrow PL emission at 0.678 eV with a linewidth of similar to 14 meV at 4 K and a clear band-filling e...

High-quality Inx Al1xN (0.71 = xIn = 1.00) nanocolumns (NCs) have been grown on Si(111) substrates by rf-plasma-assisted molecular-beam epitaxy (rf-MBE). Low-temperature photoluminescence (LT-PL) spectra of various In-rich InAlN NCs were measured ...

The optical properties of InGaN/GaN multiple-quantum-well (MQW) nanocolumns whose emission wavelength is in the yellow-to-red region (2.1 similar to 2.3 eV) have been investigated using time-resolved photoluminescence (PL) measurements. The analys...
The orientation-dependent lateral growth of InN was studied and the epitaxial lateral overgrowth (ELO) of InN by rf-plasma-assisted molecular-beam epitaxy was demonstrated for the first time using stripe molybdenum (Mo)-mask-patterned sapphire (00...

We propose an array of submicrometer mirrors to assess luminescent nano-objects. Micromirror arrays (MMAs) are fabricated on Si (001) wafers via selectively doping Ga using the focused ion beam technique to form p-type etch stop regions, subsequen...
