Yunran Wang’s paper “Precise Arrays of Epitaxial Quantum Dots Nucleated by In Situ Laser Interference for Quantum Information Technology Applications” was published in ACS Applied Nano Materials (3 (5), pp. 4739−4746 (2020)).
We have demonstrated that high structural and optical quality quantum dot (QD) arrays can be grown by a combination of in situ laser interference patterning and self-assembled molecular beam epitaxial (MBE) growth. Distinct regimes of nanoisland and QD formation were observed during the growth of InAs/GaAs (100). By optimizing the growth and interference conditions, regular dense ordering of single dots was obtained for the first time and the photoluminescence (PL) spectra of the resulting quantum dot arrays with a period of 300 nm show good optical quality and uniformity.
Congratulations!
