| Abstract(in English) | The effects of NH_4OH:H_2O_2:H_2O etching treatment of V-grooved GaAs substrate on the improvement of heterointerface uniformity of V-grooved AlGaAs/GaAs quantum wires (QWRs) were investigated by atomic force microscopy and micro-photoluminescence measurements. It is found that surface roughness on the initial V-grooved substrate generated during V-groove preparation processes can be greatly reduced, and the heterointerface uniformity of the grown AlGaAs/GaAs QWRs can be greatly improved by the use of NH_4OH etching treatment. |
