Presidential Fellow (August 2022 - Present) 

Research Projects:

Nanofabrication of Liquid Metal: 

• Developed a fabrication technique to pattern Gallium-based liquid metal (LM) nanostructures with the highest resolution (100 nm) to date.

• Integrated processes like lithography, physical vapor deposition, and reactive ion etching with the experimental setup and for the first time, fabricated large arrays of liquid metal nanophotonic structures with high yield.

Tunable Photonics Display: 

• Fabricated sub-100 nm nanophotonic structures on SiO2 substrate using e-beam lithography, e-beam evaporation, and dry etching processes for photonic display and nanoparticle sensing applications within visible spectra.

• Utilized ALD of HfO2 and Al2O3 for depositing a few nanometer thick oxide layer on the fabricated nanopatterns to achieve Au on "liquid metal mirror" photonic resonator. 

Quantum Well Infrared Photodetector (QWIP): 

• Used EBL and PVD to fabricate Au nanoribbon-based plasmonic resonator on MBE-grown GaAs quantum well sample, which couples the intersubband transition to the plasmonic resonance for enhanced photon absorption.

• Utilized NH4OH+H2O2 for wet etching of GaAs substrate and HF for wet etching the AlGaAs etch-stop layer.

Graduate Teaching Assistant (August 2022 - Present)

Teaching Responsibility

• Facilitated undergraduate courses by leading recitation and laboratory sessions, clarifying course material, answering questions, and offering academic support to students.

• Graded assignments, exams, and other assessments promptly and provided constructive feedback to students to enhance their learning outcomes and academic performance.
