Cathodoluminescence properties of GaAs/AlGaAs pyramidal cap structures with high spatial resolution
We have measured the excitation position dependence of the cathodoluminescence (CL) from GaAs/AlGaAs pyramidal cap structure with the spatial resolution of 30 nm. The CL spectra strongly depend on the excitation position and the CL peak, the intensity of which is the maximum under the excitation at...

| description | We have measured the excitation position dependence of the cathodoluminescence (CL) from GaAs/AlGaAs pyramidal cap structure with the spatial resolution of 30 nm. The CL spectra strongly depend on the excitation position and the CL peak, the intensity of which is the maximum under the excitation at the top of the pyramid is efficiently strong even under the excitation at the position which is 500 nm away from the top on the ridge. This result suggests the effective energy transfer toward the top of pyramid. (© 2006 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim) |
