Thinner Means Stronger: How Ultrathin Films Beat Magnetic Fields ⚡ экспресс
Original: "g-Factor Enhanced Upper Critical Field in Superconducting PdTe2 due to Quantum Confinement"
Scientists have found that a 19-nm-thick PdTe₂ film withstands magnetic fields 10 times stronger than a thicker sample.

Superconductors are usually destroyed by a magnetic field. But physicists found a loophole: if you make a PdTe₂ film thinner than 50 nanometers, the field it withstands soars 13-fold! Quantum effects alter electron behavior, opening the door to superconducting devices in strong magnetic fields.
🎯 A 19-nm-thick PdTe₂ film is five times thinner than the shell of the flu virus. Individual layers of this material can be peeled off with adhesive tape, paving the way for flexible superconducting electronics.
