Engineering Room-Temperature Superconductivity
We have built semiconductor process equipment since 2005. We now build superconducting materials: from published theory to finished film.
Theory we wrote. Materials we make. Equipment we build.
Hyunsung TNC is a manufacturer first. Since 2005 we have built process equipment for customers including Samsung Electronics, and in 2017 we turned that discipline to superconductivity. The theory came out of the work rather than ahead of it: MEL (Modulated Electron Lattice) Theory is our own, it is published as two preprints, and it is the foundation of our patent portfolio.
We have room-temperature superconductor candidates in hand. In our own laboratory, a Cd-based candidate shows a superconducting transition at 37.1 °C (310 K), at ambient pressure. What follows a result like that is not a press release, it is the work: reproducing it across batches, putting samples through independent laboratories, and holding it to the standard a claim this size has to meet. That work is underway now, and the theory behind the candidate is already published for anyone who wants to attack it.
On that foundation we are building SuperMatics, an AI-driven superconductor design platform spanning composition design to production. Hyunsung TNC is a major investor in SuperMatics Inc., its U.S. company, and licenses MEL Theory to it. The work is institutionally connected: a research collaboration with Ewha Womans University, a facility use agreement with BNC Labs at the University of California, Berkeley, an R&D partnership with CAN Superconductors, and intellectual property strategy with Wilson Sonsini Goodrich & Rosati.
Grounded in Theory
Hyunsung TNC has independently developed MEL Theory, a quantitative framework for the formation mechanism of high- and room-temperature superconductors that conventional BCS theory does not address. Applied to real YBCO and BSCCO superconductors, its simulations reproduce measured transition temperatures and doping dependence. The framework is public and checkable, set out in two preprints: arXiv:2512.03368, “Short-range modulated electron lattice and d-wave superconductivity in cuprates”, and arXiv:2601.14500, “A Modulated Electron Lattice (MEL) criterion for metallic superconductivity”.
Corroborated Independently
The mechanism MEL Theory rests on, charge order and superconductivity reinforcing one another rather than competing, was reported independently in Physical Review Letters in 2026 by a team at Stanford and SLAC. We had no part in that work and no stake in its answer. In our own laboratory, a Cd-based candidate shows a superconducting transition at 37.1 °C (310 K) at ambient pressure. Reproduction across batches and verification at independent laboratories are underway now.

Engineered for Production
Our patented CTLA (Circular Target Laser Ablation) process synthesizes and deposits a superconducting thin film in a single step, holding compositional variation within ±0.5% and impurities at the ppm level from the raw-material stage. It runs on equipment we designed and built ourselves, which is the half of this problem most research groups have to buy or borrow.
Protected by Patents
Twenty-one filings, two of them granted in Korea: the room-temperature superconductor candidate material (10-2359995) and the CTLA deposition process (10-2523480). Foundational filings for MEL Theory and for the design algorithm behind SuperMatics have entered the national phase in the United States, Europe, Japan, India and China, with trademark applications filed for the platform.
