Summary
Experimental physicist with more than a decade of hands-on work taking quantum and semiconductor devices from design and cleanroom fabrication to low-noise cryogenic measurement. Recent work on topological superconductivity in Fe(Te,Se) nanoscale ring devices for fault-tolerant quantum computing. Earlier, CMOS-compatible 2D-material and hybrid organic–silicon optoelectronic devices. Now combining this experience with AI for science and technology.
Core skills
Device fabrication and structural characterization: cleanroom nanofabrication, process development, electron-beam lithography (EBL), focused ion beam (FIB), scanning electron microscopy (SEM), atomic force microscopy (AFM), reactive ion etching (RIE), Raman and optical spectroscopy, thin film deposition (PVD, e-beam evaporation, CVD, PECVD), 2D materials, wide bandgap oxides, organic semiconductors, topological insulators, and topological superconductors.
Electrical characterization: DC/AC semiconductor parameter analysis (SMU, LCR, etc.), optoelectronic characterization tests (photovoltaic cells, optical detectors/sensors), low-noise/precision measurements (lock-in amplifiers, Atto-sense modules, low-temperature LPFs), cryogenic systems, quantum transport, phase-sensitive magnetic/flux measurements.
Computation, data analysis, and automation: Python, Mathematica, LabVIEW, KLayout (layout/mask design), statistical analysis, instrument automation.
Experience
- Built an end-to-end fabrication process for hBN-encapsulated, nanoscale superconducting ring devices (EBL, FIB, RIE, thin-film deposition).
- Upgraded a closed-cycle cryostat and designed cryogenic low-pass filters; automated low-noise, phase-sensitive measurements in Python.
- Demonstrated half-integer flux quantization, coherent edge transport and intrinsic magnetization of the condensate in Fe(Te,Se); 4 first-author papers and preprints.
- Collaborated with Brookhaven National Laboratory, Stony Brook University and NY Creates; invited talks at LPS and the Gordon Research Conference.
- First chemical-vapor-deposition growth of borophene, a one-atom-thick metal for 2D interconnects (ACS AMI, 100+ citations).
- Measured carrier transfer across graphene–silicon junctions (10⁶× slower than Au–Si) and derived the 25.5% efficiency limit of graphene/Si solar cells.
- Developed position-sensitive detectors and self-powered photodiodes on PEDOT:PSS/silicon (APL Editor’s Pick; 10⁶ V/W responsivity).
- Nanostructured solar cells and photodetectors; Monte Carlo and COMSOL modeling of charge transport and plasma growth.
