Building a Quantum ESPRESSO GUI on a Tablet

So here’s something I didn’t expect to be writing about this semester. I’m a first-year CSE student. I do most of my coding practice on a tablet with Google Colab open in the browser. And somehow, over the past few weeks, I ended up building a working simulation of BURAI 3; the GUI for Quantum ESPRESSO, specifically for visualizing the band gap of MoSe2 (Molybdenum Diselenide). A real 2D material being studied for next-gen transistors and solar cells. Full disclosure upfront: I used AI assistance, referenced published papers, leaned on the Three.js documentation, and took workflow inspiration from existing GitHub repos. But I understood what went into it, and that’s what I actually want to talk about. Because here’s the thing - nobody tells you in first year. Understanding something and building it from scratch are two completely different skills, and both are valid. Why This Project My professor mentioned MoSe2 band structure project. Something about how it has a direct band gap in mo
