TL;DR: In this article, the electronic and polarization properties of columnar columnar InzGa1−zAs quantum dots (CQD) with high aspect ratio embedded in an InxGa 1−xAs/GaAs quantum well were analyzed.

TL;DR: In this article, the authors investigated the deepness of contactless electroreflectance (CER) probing (d CER ) and found that the d CER is much smaller that the penetration depth of the probing beam (d λ ∼ 0.5-1 μm), and for samples containing a sheet of carriers (a two dimensional electron gas at an interface or a delta-doped monolayer) the dCER is reduced to the distance from the sample surface to the carrier sheet (e.g. 20 nm).

TL;DR: In this paper, multicolor emission is reported from ultrasmall (<10 nm) β-NaYF4:Eu,Tb nanocrystals depending on the excitation wavelengths or emission detection delay time.

TL;DR: In this paper, the authors studied the energies of E0 and E0+ΔSO transitions in In0.53Ga0.47BixAs1−x alloys with 0.

TL;DR: In this article, a GaSb-based type-II quantum well (QW) structures and interband cascade lasers (ICLs) were investigated with regards to the dependence of emission wavelength on active QW thicknesses.
