Hi, I’m Haoming! 👋
| Ph.D Candidate in Physics | Peking University |
Nice to meet you! I’m a physics grad student who loves playing with light, materials, and code. When I’m not in the lab or running simulations, you’ll probably find me outdoors somewhere.

🌱 My Journey
I started at USTC (School of the Gifted Young, 2017-2021) studying physics with a CS minor, and now I’m pursuing my Ph.D. at Peking University (2021-present) in atomic and molecular physics.
Along the way, I’ve become obsessed with perovskite optoelectronics—both making devices in the lab and understanding them through simulations. It’s pretty cool to see how atoms arrange themselves and how that translates to things that actually light up or capture energy!
🔬 What I Do
In the Lab 🧪
Perovskite LEDs & Solar Cells
- I’ve worked on patterned perovskite micro-LEDs that can form images
- Built solar cells that stay stable for over 1000 hours at 85°C (that’s hot!)
- Achieved 24.3% power conversion efficiency—getting closer to those theoretical limits
- Even built an automated testing system because manual stability tracking was… tedious 😅
Cool Experimental Stuff I’ve Done:
- Built optical tweezers and a confocal laser scanning microscope from scratch
- Laser-ablated fiber microcavities (yes, with actual lasers!)
- Characterized materials using XRD, SEM, PL, PL mapping, GIWAXS, XPS, UPS, CL mapping, TRPL, EDS, UV-vis, AFM, KPFM, IPCE, TA, EQE, FTIR… (if you know, you know 😄)
On the Computer 💻
Computational Physics:
- Used CP2K, VASP, Gaussian, and Phonopy for DFT calculations
- Calculated transition states with CI-NEB
- Studied binding energies of molecules and solids
AI & Coding:
- Fine-tuned Uni-Mol and other ML models for materials discovery
- Build agents and LLM-powered tools (big fan of Claude Code!)
- Full-stack web dev with React + FastAPI
- Love using chemoinformatics tools in Python

🏆 Some Recognition
- Outstanding Core Member, PKU Project 1000+ (2022)
- Teaching Assistant for Demonstration of Physics (2023) and Mechanics and Thermodynamics (2020)
🌲 Beyond the Lab
Life’s not just about physics! Here’s what keeps me sane:
🥾 Hiking & Camping I’m a leader at the PKU Hiking Association and have organized 10+ expeditions. There’s something magical about being on a mountain trail at sunrise. If you’re into hiking, let’s go climb a mountain together!
🚴 Cycling Active member of the PKU Cycling Association. Nothing beats the freedom of flying down a road on two wheels. Want to join for a ride?
🏃 Running Training for longer distances one run at a time. Always happy to have running buddies!
📈 Stock Market I enjoy following markets and thinking about investing. It’s a different kind of puzzle—one where you never have all the pieces, but you still have to make decisions.
