Subject: Calculation of elastic strain for the displaced cubic and interstitial cubic center of mass (BCC) alloy under pressure was constructed using the statistical moment method.

Mentor:

• Associate Prof. Nguyen Quang Hoc, Faculty of Physics, Hanoi National University of Education.

Subject: Realization of 3D sub‑microstructures on SU‑8 using low‑one photon absorption lithography

Mentor:

• Associate Prof. Ngoc Diep LAI, lecturer at ENS Paris – Saclay, France.
• Associate Prof. Danh Bich DO, Head of Faculty of Physics, Hanoi National University of Education, Viet Nam.

During my 3‑month internship at ENS Paris‑Saclay, I learned how to use a confocal experimental system for the Direct laser writing (DLW) with Low‑one‑photon absorption (LOPA) method to fabricate 3D polymer structures. These structures were fabricated as photonic crystals that can be applied in a variety of applications. During this time, I learned not only knowledge but also how to work in a professional laboratory.

Subject: Manipulation of solid-state single-photon emitters by vertical Mach-Zehnder interferometer.

Mentor:

• Associate Prof. Ngoc Diep LAI, lecturer at ENS Paris-Saclay, France

After 4 months studying at the MONABIPHOT Master program at ENS Paris-Saclay, I was accepted to do my internship at LUMIN laboratory with professor LAI until now. I was fabricating vertical Mach-Zehnder interferometer, which is a new direction, using LOPA technique. I also learnt to do the theoretical calculations and simulation on Lumerical FDTD.
