我们利用阴极发光技术定位液滴外延量子点，精度小于或接近50 nm，然后利用电子束光刻技术在液滴外延量子点附近制造纳米天线。阴极发光进一步用于证明天线作为其长度对点发出的光的函数的影响。实验结果与数值模拟结果吻合较好。(C) 2013 AIP出版有限责任公司
We use cathodoluminescence to locate droplet epitaxy quantum dots with a precision less than or similar to 50 nm before fabricating nanoantennas in their vicinity by electron-beam lithography. Cathodoluminescence is further used to evidence the effect of the antennas as a function of their length on the light emitted by the dot. Experimental results are in good agreement with numerical simulations of the structures. (C) 2013 AIP Publishing LLC.
